Level 5, during regular tavern play all the customers suddenly locked in place.
Drinking/eating animations continued.
Customers continued to order drinks from table
2 customers became stuck at the bar, the rest in their seats.
Went outside/inside a few times to see if that fixed it, It did not.
After closing, all customers stayed put, but all reputation points added.
After going to bed and saving, customers still stuck in same spots next morning.
Exiting entire game and re opening did make them go away. I will let you know if they get stuck again
