Error Message

[rhyhart]

Hey guys whats up I was playing mugen and when I picked a character mugen freaked out and a error message popped up saying this,
"Assert failure in charsel.c line 3162"
I'm not sure what that means but it happened with a few of my characters and so please help me out here.

That could be a coding problem..

With what particular characters does it happen with..?
