Persona 5 [NPJB00769]

Interesting find. I wonder what the CPU disassembly around this instruction looks like; might explain the check failing.

I don't know enough to understand why that check is there, there is probably some kind of assumption but it doesn't seem right. The check is run right after creating a new thread, and look how many times it "fails", and yet the game runs... Maybe it is some kind of weird edge case or something, I might have a look later.
