[Other] Stuck After Editing Intro Text (HELP)

I was making a hack of Fire Red and used the tool Intro Text Editor. It worked fine, and the players house that you get spawned into after going through the intro loaded perfectly. After going outside of the house though, everything was just the border block of the town.

I changed the text back to what it was originally was by copy and pasting it from a vanilla Fire Red rom but nothing changed. Is there a way to fix this?
