Okay, so I think it may have to something to do with not starting the battle with a total of four party members. I added Suki and its fine now. Thank you for trying to figure it out, you the real mvp. NOW FOR THIS FIGHT!!!
I'm glad you found a workaround!! Yeah, it seems to have something to do with who's in your party, but if you downloaded "Rxcovery v5.1.zip," that bug shouldn't be happening no matter how few people are in your party. I'll continue trying to figure this out. Thanks so much for being patient!
