So, now I'm getting this message every time Kusanagi goes up against Knuckles8864's Orochi Iori.
Spoiler, click to toggle visibilty
Whenever the match starts, that error message appears. Both Kusanagi and Orochi Iori have their own slots in the roster, and it only happens with those two. Normal/EX Kyo vs Normal/O. Iori and Kusanagi vs Normal Iori don't give me that message at all. I know jack-splat about MUGEN coding so I have no idea what's going on lol
Edit: Another thing I just noticed relating to intros with Orochi Iori, both EX Kyo and Normal Kyo have a flame appear in the air behind him during their intros.
