Bees freeze if they cannot execute their current AI task / Bees don't seem to have a wandering AI

Can you run /data get entity @e[type=bee,distance=..5,limit=1] while near the bee and post the result here?

Here you go:

How do u copy the command output? I got the same behaviour on a bee and want to help 🙂

I couldn't copy it from chat or a command block output, but if you look at the bee and press F3 + i you'll copy the exact same data to the clipboard 🙂

Thanks 😃 Here is my bee

Tbh I compared it with a normal functional bee and there is no difference at all

@unknown, 19w41a is already marked as affected.

I still cannot reproduce given the steps provided - a world save would be extremely helpful in bringing me closer to solving this. One note - AI stops functioning below y=0 and acts weird above y = 255. I see one example posted is between those values, but most of the examples given are about bees going above or below the world height limits, which is not really a valid use case / test case.

I've attached a world I used to reproduce this issue to this ticket. Also, I recorded a short video of this issue, which you can watch here: https://youtu.be/ZpfFTlzL7Co

As you can see, the bee is never above 255 or below 0, but the void world was just used as a case to demonstrate that this happens whenever a bee doesn't find its target for a while. This should work in a regular world without any flowers and without any bee hives as well.

Can confirm this happens below y = 255, this behavior tends to be triggered frequently after a bee leaves their home unexpectedly (Ex. taking the honey or honeycombs from the hives/nests), but this can still happen in both ways (Naturally without any provocation or due to the explanation I gave previously)

Basically instead of aim towards a flower they begin to fly very high till the point is impossible for them to track a flower due to the pathfinding limitations, that's why this bug gets reproduced in most cases by a bee without pollen, can confirm too this is not the case if a bee already has pollen + is far away from the home, they can track their home back from a decent amount of far blocks.

Thanks for the info and world save, that really helped in tracking this down!
