Lord J's FF6LE 'Rouge Version'

Hello all

I was working with this program and it does what it intends to, however I am experiencing a crash issue. I originally made small minimap edits to South Figaro and when I got to the Serpent Trench for the first time the game crashes. I went back to the pre-mapedited version and the game runs fine, so I tried opening that rom in the editor and just saving without making any edits. The game now runs but just goes to a black screen where the ST background music continues to play. I tried this even on a fresh non-altered rom with the same results.

I tried to do some research on the source of any issues but couldn't find anything, so any help offered would be greatly appreciated, thanks in advance!
