Having issues randomizing FE7

Hey, everyone. I’m trying to do a playthrough of FE7 with randomized recruitment, but my game keeps crashing on Chapter 12. (i.e. resetting or locking up)

Here’s the randomizer I’m using:

I know the thread is recommending a different randomizer now, but that one doesn’t have randomized recruitment yet, which kind of takes away the main thing that makes randomizing Fire Emblem games fun. Can anybody help me? Am I using a bad ROM?

A bit unrelated but it would be cool if Circles did a self-randomizer of fe6 and fe7 too
