Post-World Event error

Hello everyone, happy 2026!

I’d like to ask for a little help. I’ve been playing this ROM for ages and I discovered an internal bug that’s messing up several chapters.
It turns out I have a Post-World Event that’s not in the assigned address. It appears in two consecutive chapters, and if I delete that event, the game uses the Post-World Event from before the deletion to continue the loop.
You’re my only hope. I’ve tried everything, but I don’t know exactly what I changed, and before starting from scratch again, I want to be sure there’s a solution.

Thanks!
