I can't seem to get a jobless villager to take the beekeeper job when a beehive is available.

If you have buzzier bees alongside this mod, then”beehive” block becomes “oak beehive”, and thus doesn’t register as a proper job block.

it may be affected by a possible conflict with Never Wanted or Needed, which uses a different beekeeper model and job block. Either way NWoN’s beekeeper appears to be easier to work with (lower xp requirements for rank ups)
