Summary of Villager bugs as seen so far

Alright, this is gonna be the last one I do today; I've messed around with villages for a while now and I think this is all the bugs.

1) Villagers don't seem to know when a bed is already occupied.
As a result, they often attempt to get in beds that have already been claimed, instead of continuing to search for an available one. This is probably the most important glitch, since I'm sure it also applies to if a player is sleeping in a bed. No more bad roommates, please.
(Reported elsewhere, but I'm leaving the original text just in case.)

2) Farmers don't harvest crops.
This can't be healthy for any of them, and is probably the second most important problem. There are two fully grown farms, and the farmers just seem to be hanging around the composters not doing anything about it. I feel like this is a bug since there's no place in their schedule for them to be able to harvest.

3) Villager trade system seems to break with shift-click.
Shift-clicking on a villager trade invariably makes the item "out of stock," but only gives the player one item. (Sometimes it consumes more items from the player than necessary.)

4) Villagers don't go inside when it's raining.
They're very responsible citizens. Too responsible. They continue carrying out their duties, even when it's thundering and raining like Nether outside. I don't believe this is intentional.

5) Farmers get stuck in composters.
This is pretty self-explanatory. For some reason they don't know how to jump to get back out. This can be easily remedied, however, by sticking a trapdoor on top of the compost bin.

6) Iron golems wander off from the villages/ despawn.
I'm not sure which one it is, since he always disappears when I'm not watching. Slacker.

7) Villagers seem to stay out late.
I don't know if this is intentional, but villagers tend to stay out a bit after the sun has slipped below the horizon (at sea level). I was told they were supposed to go home a bit before sunset. But maybe I'm wrong.

8) Wandering Traders are a little odder than they should be.
Their llamas don't despawn with them, and their despawn times are strange. I'm not sure about this one in particular, but I think their timers are off. Sometimes they hang around for a really long time, and sometimes they leave in such a rush that they leave their llamas behind. That or they're not wandering off. There's two that have been sticking around the village for some time, while they should be... well... wandering.

That's all for now... I hope.
