This just happened to me last night. Right after the amplified Kold Shoulder I became Reptile. The invisibility went away on hit though. NRS please fix. I can't imagine if this happened in tournament. lol
Just wanted to add that it happened again last night but this time it was only the regular Kold Shoulder and not the amplified version. Seems to only happen in the corner as well. Just trying to kollect as much info on it as I can. I'll try to post some of the recordings when I have more time.
So, I guess these just prove that positioning on screen and whether or not the Kold Shoulder is amplified doesn't really matter.
I still have yet to find a way to do it consistently. (though it does happen quite frequently)
Hopefully these shed just a bit more light on the issue.
