Sorry if this is old news but I seem to have trouble with this site's search function.
I was in training mode with Ibuki and came across something odd. If you have auto-block on and can get your opponent to take a hit prior to activating Ultra2, I guess the cpu glitches or something similar. After auto-block takes effect, if you whiff the first two hits the computer cannot block her roundhouse animation. Its really odd, with all guard or cpu set to 2nd player it can be blocked. Its only the computer that can't seem to block it.
Don't know if there's any importance to it or not but figured I'd share it with all of SRK.
Interesting sidenote: the guard animation and effect color appear in place of the Orange that should actually appear.
