FF6 Advance Hacking: Event Trigger Problems?

I gave that a try, yes, and it seems to have worked.
When you load a GBA rom in FF6Tools it tells you that you should rearrange the triggers because some of them are stored separate from the others and that its better to do that if you wish to modify them. But it seems like that just breaks every trigger in the game. That's something the creator of FF6Tools might want to look into.

I'll let him know!
