I had 2 villagers close to getting totems at the same time, both waiting for building.
Then a totem arrived for the lower of the 2 builders, although his name tag still says Adept and he has since stopped gaining in the skill.
Poor old Granny is also stuck with building higher than her master in farming, yet she is still labeled as adept builder.
Consequently I can't get my gong piece out of the crate

This all happened yesterday, the pc was off over night, game logged out etc etc etc.
