Graphical glitches on overworld map while walking

The only things I've done so far is:

-expanded rom to 32MB with FF3usME
-changes to overworld map
-some sprite modification (none to palettes)
-applied vanish/doom, evade, and rippler fix patches
-changed a few items in shops
-disabled the veldt trait on all tiles that had it

I haven't messed around with script/hex editing at all yet because I know that I don't know what I'm doing there, haha


Edit: looks like deleting exits on the world map is what's causing it.
