Sulani is broken

I've had played sims swimming in sand and even docks.  I've had sims walking underwater.  Of course the Fishing signs don't work.  NPC sims walk onto lot, as if a public beach.  Employees do not follow directives (so far only Sulani).  NPC sims who are not Father Winter come into house and get a glass of water then wonder a round, usually in the middle of the night. I caught a screenshot of 2 NPC sims swimming in a canoe.  As a residential World Sulani is unlivable.  😥
