Looks like Tiny Allies may be the cause by using convertTo method during worldgen entity spawning. Repurposed Structures spawns entities during worldgen the same way vanilla does when spawning structures with entities. So it’s likely you would see this same issue even without repurposed structures when spawning structures with entities in them
That makes sense. I will try to remove Tiny Allies and see if the issue occurs again. Thanks.
