Bees freeze if they cannot execute their current AI task / Bees don't seem to have a wandering AI
The bug
Bees freeze if they cannot execute their current AI task and cannot pathfind to their current target, such as a player, a flower, or a bee hive/nest. This is probably the case because bees don't have a wandering AI and completely rely on their current target(s) for pathfinding.
This issue seems to occur in multiple different scenarios:
- Bee cannot find a flower or pathfind to a flower
- Angry bee cannot pathfind to its attacker (
MC-159676) - Bee cannot find a new home hive/nest or cannot pathfind to its home hive/nest, either after having pollinated a flower or after not finding a flower to pollinate
The last case appears to happen most often. It seems like if a bee has not pollinated a flower for a while (about 3600 ticks, maybe a bit more) and does not have a home hive (which happens often, see MC-159418), this issue occurs.
The fact that the bee does not have any animation when being stuck in the air is a client-side issue and also occurs in other circumstances. That issue is tracked in MC-159518.
To reproduce
There are many ways to reproduce this issue, however the most common way this happens is if a bee is too high up in the sky. That case is easily reproducible using the following steps:
- Spawn a bee at the top of the world, way above the ground
- Follow the bee for a while, until its TicksSincePollination value is at least 3600
- Wait a bit longer

Very ImportantCreated Issue:
Bees stop flying randomly
I was playing around the bees, and as I was trying to see if they build nests if there aren't any in close proximity, I noticed that one of the bees had frozen in mid air.
When I bounced into the bee it started waving its wings for a short moment, and then froze again. Not entirely sure why, but it might have to do with the entity update range, but I could be wrong. I wasn't anywhere near the bee for a few minutes so.
I've provided a small clip of the bees behavior.

The bug
It seems like if a bee is too high above the ground, it will stop flying and just hover in the air without any animation (see
MC-159518).To reproduce
The exact cause of this issue is unknown as of right now, but it seems to occur quite often if you're playing around with bees and a bee doesn't find flowers or a hive nearby.
If you know of a consistent way to reproduce the issue, please let us know in the comments.

See also MC-159350, which is very similar, but reproduced in a different way. Basically, every time a bee tries to pathfind, but can't find a valid path, it's standing still.

I've done some extensive singleplayer testing, and this seems to be the product of a bug and an intended feature.
Bug:
Bees will often (Not 100% of the time) fly directly downwards for a short period upon spawning. This overrides the rest of their AI, including water avoidance.
The amount is entirely random but is most of the time <15 blocks
During testing the furthest I have seen a bee fly down was an obscene 95 blocks. I have attached an image.
WAI:
If a bee is more than 1 block below the surface of a body of water, it becomes unable to move at all and drowns because bees can't swim. It may be worth noting that MC-159350 also occurs here.

Duplicate of MC-159350. The fix was that the bees would still have an animation when freezing in place instead of appearing petrified with no animation.

Attached my test world as well. I just built that structure from scratch in 19w42a, spawned five bees inside of it, and waited for a few minutes. After a while, only one bee entered and left the hive, and the other four bees remained stuck.
I assume this is closely related to, if not the same issue as MC-159350.

As per [Mojang] Cory Scheviak's comment in MC-159350:
One note - AI stops functioning below y=0 and acts weird above y = 255.

Can confirm in 20w51a, however, the comment by [Mojang] Cory Scheviak in MC-159350, states that this feature "Works As Intended".

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:

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 a lot!
Completely forgot that that exists as well. That's a much easier method!
I noticed that with Peter's bee, the flower position and the hive position are both at 0 / 0 / 0, which the bee probably has trouble pathfinding to. For the David's bee, only the flower position is 0 / 0 / 0, and it's probably currently trying to get to that flower. That might be the cause.
Can confirm; this happened to a few of my bees after testing
MC-159418.2 of my bees had this issue. heres their data
i tried to summon it at these locations and it did the same thing again. I believe it may be based on that

When moving away from certain bees, they stop moving when I get about 10 blocks away for more than a few seconds (how long is hard to measure with in-game tools, sorry). Their wings flap briefly, before freezing as well. This seems to happen to all bees which have been in contact with hives, nests, flowers, and have been bred by the player, however I haven't yet seen it happen with newly spawned bees from a spawn egg.
Contact with any other entity (including other un-frozen bees) makes them resume moving briefly, before freezing again as before. Going within 10 blocks of bees in this frozen state with a flower in either hand makes them resume normal behavior as well.
Here is entity data from bees in each state:

It seems to me as if this happens when a bee is searching for new flowers or a new hive, and as a result flies high up into the sky. At some height above the ground, the pathfinding algorithm appears to fail, causing the bee to freeze.
When teleporting all bees that are up in the sky to the ground, they seem to start working properly again.
The fact that the bee doesn't play any flying animation while standing still is now covered in this ticket:
MC-159518I've changed the ticket up in order to include all of my new findings. If anyone has more information, please post a comment, that would be very appreciated!
Edit: I found out that this happens if the bee has not pollinated a flower for a while and tries to return to its home hive, but doesn't have a home hive yet. Included that in the ticket. Sorry for the updates everyone! But I believe I've found the exact cause now.
I have found really similar bug. Bees ( both with and without pollen) can fly below y = 0 and sit in the void.
I suggest making it impossible for bees to fly below y = 0 by editing bee PathNavigator or AI;
https://bugs.mojang.com/browse/MC-159769?focusedCommentId=578283&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-578283
I've rewritten this ticket again in order to include all cases in which this occurs.
While this is most likely a valid bug (still have to repro for myself), no mobs use AI below y=0. Do not use a void world as a testing ground because this is an invalid test case.
The repro steps I provided in the description should work in any default world.
Cannot reproduce in 19w38b. Assuming fixed?
I just updated my main world to the most recent Snapshot (19w38b) and have found that this issue has not been resolved. Before I updated, this had never happened but now my bees keep freezing. I’ve had two freeze high in the air and one freeze under a tree. I did fix one by hitting it and getting it to follow me. But it’s strange how this would only begin occurring with the latest update.
Can confirm for 19w39a
I can confirm that this happens in 19w39a. I have managed to breed a lot of bees and at one point, the bee wanders too far from their hive that they'll either wander aimlessly or if high enough it just freezes mid-air.
it still happens in 19w39a
Confirmed for 19w40a
aaaand 19w41
Cyan Penguin, 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!
