you're very welcome, and again thank you so much for this valuable info!
That's super weird! logically the game should also fade back in after it fades out, I checked the events and everything.
But I might have a couple theorizes as to why this might be happening... hopefully i can fix it. It might have somethin to do with multiple background processes clashing and canceling each other out.
And when you said it "froze" on the fight screen and during the Hide n' Pounce minigame. Did it go black? or was the screen just not moving? or did both happen?
