Online match crashing - The Game Session has Desynchronized

This crash is caused by pressing down two or more buttons while in the middle of a combo during online play.

For example, using scorpion, if you are performing the 3 kick combo (fk fk bk), pressing fk-fk- then any two buttons at once will cause the match to crash and the "desynchronize" message to pop up.

This crash also occurs using a wide variety of other characters (which I haven't been able to pin down due to PSN outage).
 
OMG, are you freaking serious? This problem has been plaguing me, it is so frustrating!!! How do you know its because of the pressing 2 buttons while in a combo theory?

I've never been this frustrated at an online game before. It takes a good while to find a match, and then once I'm in it, it runs relatively great and lag free. Then all of a sudden, just when I'm in the middle of a wicked combo, GAME SESSION HAS BEEN DESYNCHRONIZED!!!!!

This happens randomly with all my characters, on Xbox Live, with a 30MB up/down fiber internet connection. PLEASE FIX THIS, NRS!!!!!!!!!!
 
I stopped playing this game online cause the online is just freakin terrible.

Anyway, do Sonya's military stance grab combo with the punches included, before the boot... and the game will desync. Doing the punch part of the combo grab is a two button simultaneous press.
 
You know, I don't buy this 2 buttons during a combo thing causing this problem. I come to this conclusion because the game contains many combos that require pressing 2 buttons simultaneously.

But at least somebody else besides me has been desynchronized. It happens to me about 50% of the time. Its enough to make me keep playing because sometimes it works great, but then......... DESYNCHRONIZED!!!!!!!! WTF!!!!!!!!!!!

edit- @Action KungFu - So you've experienced this and can duplicate it consistently? I'll try some Sonya combos and see if I can desynchronize on purpose. Unless it happens by accident first.

Man I hope all you guys will be able to find people and a scene to play with offline. This is just not right the hell they are putting you through online.

That is very very odd if it's true. wtf
 
yeah, its bs and a half. I've got a couple of people to play offline with, but thats only once a week MAYBE. and just a few hours. Not going to get better at that rate. It took me over 200 hours of online play with SSF4 before i was even just bad and not flat-out terrible at the game, and then another 100 or so hours of offline play to get "ok". If I can't get that kind of time with mk, i will never get "ok" at it, but maybe i'll get there by the time mk10 comes out and some skill will transfer...

sad state of affairs though.
 
Guys, I just found a thread about this at the official MK forums, and these people are saying it might be caused by 3rd party controllers. Can you guys post what kind of controllers you're using? Apparently Mad Catz TE's do it, and I've been playing on a Tekken 6 Wireless arcade stick myself. I do also have a homemade stick with a pad hacked official microsoft wireless controller in it. I'll try some matches as soon as I can get out of work, and let you know my results.
 
Test results are in. Official MS controller does it too. Here are my button mappings...

FP = X, BLK = Y, BP = RB
FK = A, TAG= B, BK = RT

It just happened to me in a match as Smoke, while I was mashing the shit out of FP and BP simultaneously.

This NEEDS to get reported on either the MK forums, to their admins, or on boons twitter.

This is very gamebreaking, I think it happened to me many times and is the reason I have undeserved disconnect marks.
 
There's a 5 page thread about this at the official mk forums technical issues board. I figured out a work-around fix for this though, although its ridiculously inconvenient...

The problem is with the game's buggy button mapping system. It only happens when you use a control scheme that is not default. I switched to default controls and have not had a single instance of this desynchronization problem since.

Problem with that is, I can't play on default controls on my arcade stick. So, basically I re-wired the buttons on my arcade stick to put the default controls on the buttons that I need them to be on. So now my arcade stick layout is like this:

X RT Y
A RB B

So this kills my controls in all other games, but I don't have any other games that crash when you re-configure the buttons. If MK is your game, then try this fix for the time being.

Could someone link to the official forum thread?

Some buddies and I have been having desyncs every single time I use a Quan Chi combo. We've since barred that combo from the game....... It isn't every kombo that uses two buttons - back A, X+Y (low kick to double fisted overhead) works 100% of the time without issue.

Some of my notations might be off below, so I'll write a description in (). Between the game having Tao Feng controls (wtf is a backpunch?), the controls not being traditional kicks-on-the-right and having to remap.... I don't know which button is which anymore. :p

The combo is (Xbox, normal button config) f+X, Y, X+Y. It *usually* works fine on the ground, although it sometimes disconnects. When it desyncs, the screen freezes on the frame where Quan Chi is stuffing the skull into their belly right before they kind of "fall" on to his shoulder. Estimates are in bold.

(Anything) into Zombie Walk to back Y, X (slap, uppercut), f+X, Y, X+Y (skullybelly desync). Desyncs 90% of the time in 1on1, 100% in King of the Hill

Back Y, X (slap uppercut), f+X, Y, X+Y (skullybelly) Desyncs 75% of the time in 1on1, 90% in King of the Hill

Zombie walk/nothing to Neutral jump punch, f+X, Y, X+Y (skullybelly) Desyncs 75% of the time in 1on1, about the same in King of the Hill

Here's some more information:
SFIV TE Stick
Buttons remapped (Y and B are block and throw)
The desyncs always happen in King of the Hill
The desyncs sometimes happen in Private 1 on 1

Also, I wanted to ask about/complain about the "I don't have to press a button" kombos. If you want to direct me to a better place - please do. A basic description of this infuriating thing is Ermac - try to jump kick, teleport. You'll air-fireball without having to push a button.

Weird one with Noob -
Press block, then down, up (ex teleport, supposed to be down, up, block) The block animation will start, then he'll teleport.

Here are a few with Quan Chi -
Back+A, Forward (low kick to Zombie walk)
Back+A, X+Y+A, Forward (low kick, overhead, zombiewalk, very fast input)
X, X, 214 (two punches, skull fireball)

These are infuriating. If I want to Back + A, then dash in to throw... nope, zombie walk comes out.

If I do an X, X against a blocking opponent and want to dash backward and crouch block.... nope, the Disco move comes out.

Crouch block to Back + A (guard a sweep, punish with my own low turns into a teleport somehow???)

Infuriating controls.

Oh, I almost forgot.
PS -

I emailed a description of the Zombie Walk, Slap Uppercut, Skully Belly to Netherrealm a while ago before I found this thread.
 
I think it's just random crappy code.

Default stick, arcade stick, default button layouts. Doing combos are not , you name it.. still happens.

The patch should be addressing this, no way in hell the Devs don't know of this. It probably happens to them when they play online.

They're doing everything they can to help this - they've said it in a press release. It is a waiting game, but NRS does care and is working on it.

Everyone needs to follow Rob's words of wisdom and at LEAST make an attempt by beginning the post in the regional matchmaking forums. You never know, it might make you never do "online" again. :)

I'm tellin' you, try default buttons. After making the switch, I've played literally 100's of games without it happening, compared to every other game desynchronizing.

Like I said, I can't play on the default button scheme, so I re-wired my stick to match defaults. Your Mad Catz TE is wired with quick disconnects, so doing this will take you about 5 or 10 minutes.

Just try it out, I want to read another success story. Maybe NRS will fix their entire button mapping system in a patch. They need to know that, more than just being inconvenient and confusing, its literally game breaking to change the buttons, and this is unacceptable.

You are 100% correct, good sir.

I actually rewired the stick Tuesday night but didn't get a chance to play more than a few matches until last night.

King of The Hill, 3 players, did the same kombo at least a dozen times, zero disconnects.

Also, strangely, jump kick, ex-teleport kombo now works online. w t h ? :)
 
I read over the thread and I didn’t see this one. I could have missed it but:

Doing Jax Ex dash punch on wake up, hit confirmed and it happens 50/50. So yeah its not that bad but in the middle of a hard match, on the verge of winning....duh desynced lol

EDIT: so far it happens on 1 v 1. Havent tried KOTH or Tag.

EDIT 2: buttons are not in deafult. I will put the buttons back to default layout and see what happens.

This is super annoying, trying to play as CSZ and im scared to do his main string 2,1, 2+1 as the desync every time. Very crappy!

Hm, haven't read this thread in a while. I had a hypothesis about what it could be a minute ago that might not be true but may as well post it if it is part of the problem:
You may have noticed that in practice mode, simultaneous button presses are not shown as such, they appear one after the other. If the button presses are stored that way, it may lend to the cause of the desyncs. Example: Cyber Sub's 2,1,1+2 combo. When you input it online, your game recognizes it correctly as 2,1,1+2, however, when the game sends the input through the server, it separates the inputs into 2,1, 1,2 OR 2,1 2,1, thus giving a different result for the other game(s) on the server, aka desync. This however, might've been coded correctly for the enhanced moves, as they work fine, but were not programmed correctly for the combo strings.

Again, just a hypothesis I devised in the last few minutes.
 
What is truly sad is that although this crash bug was widely posted the first day the game was released, 3 months later it still isn't fixed.
