I have learned too much... or maybe not enough (PDAFT Mod)

So I didn't notice Jotaro's weird jelly head in testing... guess that's why I should actually look instead of playing the game hehe. Also his left hand needs it's normals flipped. Thinking about adding more JoJo characters. But I might want to learn how to add new modules to the game instead of replacing current modules. Also not sure I can do a tutorial on this, it's way complicated and things can just break for no reason, or it feels like it.
