Ok with the discovery of Cage and Liu Kang having random advantage bugs we need to test the entire roster. If you don't know how to test here's what you do. Go into practice mode and set the dummy to always duck block. Do a move and then as soon as it hits and is blocked pause and turn block off. If they quickly stand up then duck back down you have the random block advantage bug. Try it like 10 times just to be sure. We should go through every move and every hit of a string with every character. If you will volunteer to do this for your main please post the results, if you've discovered a move with the bug or if you've checked every move and they have none.
