@BlackJax96 I'm still using the default result screen pics, so I doubt that's the cause
@Mewtwo2000 I've not had a problem with these stages before, and it seems to occur on any stage at pure random.
Thanks for the suggestions regardless though, I'm going to revert some of my changes and see if I can determine what's causing it through process of elimination.
EDIT: I took off the Peach port over Wario and it seemed to resolve the issue, or atleast I didn't encounter it during my time of playing. I still don't understand how it would affect the game without that character being in play though... Unless perhaps some of the codes necessary for the port were causing the issue? Either way, I suppose I'll just stop using it for now. Thanks to everyone who helped.
i think i know the problem probably wario or peach calls an article during result screen you should just use the no result screen articles code and try again
