it was actually the common4.pac, I dont remember when I got it or what it does
but it doesn't seem to affect anything else, thanks for replying

no , I dont have anything in koopa's (Bowser's) folder nor Gkoopa's folder

EDIT: i have more info

I can still fight, when taunting or being grabed the animation goes back to normal
I think it could be a common.pac file but I dont know which one, I have common3, 4 and 5.pac

I need help please, no matter what move I do, Bowser stays in T form, I dont have any .rel of him or textures
I'm sorry if it's a noob question
