latest.log contains flood of:

[co.te.re.RepurposedStructures/]: Repurposed Structures: Non-existent child pool attempted to be spawned: minecraft: which is being called from villagersplus:villages/bamboo/horticulturist. Let Repurposed Structures dev (TelepathicGrunt) know about this log entry.

I'm using datapack as well:

repurposed_structures-villagersplus_v2.zip https://www.curseforge.com/minecraft/texture-packs/repurposed-structures-villagerplus-compat-datapack

Fixed in v3. horticulturist villager wasn't spawning was the issue
