After a while in a world if I try to trade with a villager, the interface would briefly show up before closing immediately. This doesnt happen to all villagers, but only certain ones seemingly at random. The affected villager would wander around in the day, as if it was unemployed/a nitwit.

Closing and Opening a world doesn't change much, right-clicking the villager would now skip the interface pop-up, and instead act like I am trying to interact with something that simply doesn't have a function.
