Since the new update that enable to player to place cozy lanterns, villagers seems to be particularly attracted by this block (like real mosquitoes). They often literally run into lanterns and then be stuck into them.
When the phenomenon occurs, the villagers won't move until you break the lantern / push them out of the block. They won't get into house at night, or even try to flee if zombies attack them. At this moment they stop their activities, they just can barely socializing with other villagers.
I also noticed that some villager are easily blocked by all sorts of barrier block (wooden or stone). When it happens, the villager stop his path or his activity it want to initiate. In my attachments, I set a screenshot of a farmer which want to collect a potato, but its behavior seems to ignore that there's a cobblestone barrier on its path. The farmer was stuck in place looking at the potato plant for minutes, until I helped him to reach its plant by breaking the barrier.
This kind of issues are very annoying, because most of villagers dead being attacked by zombies which they can't (/ "don't want to") hide from.
Please, take a look.
