Soft reset mob spawns

[Ciderpress]

How exactly is this coded? Why does lodi always spawn on soft resets but seemingly nothing else does? Do mobs with windows like angry goblin open new windows, or does it resume the same timer it had already been on before the reset? Or what the hell? How does this work?
