Hello!
Well, it's me again and i have really weird situation.
After using "mug" command in the battle, an animation for the next inputed comand of anyone on the battlefield (including enemyes), just being skiped (but it also checked by system that action actually performed).
So, for example, if i use "mug" by vincent, then performing animation for next action, like cid's limit break, would not be seen, but a damage to the enemy would be done (thus, there is'n animation for damage counter over enemy too)
Bootloader0039 patch pack.
Also, i tryed to reinstall fully ffvii - same problem.
