Finally assigned! Hopefully gets fixed for 1.14.1
I was waiting for so long to see this Issue catching the attention of Mojang, specially in this Update where you can find it more commonly with Illagers and Villagers.
Hopefully MC-96319 gets squashed too, it's another Bug that can be reproduced more commonly in this Update.
Duplicate of MC-96319. Please note that bug reports are only accepted in English.
MC-96319 is also getting fixed. And this Issue is directly the problem with Mobs Pathfind not regarding some Blocks as obstructions (Bamboo, Lanterns, Flower Pots, Mob Heads, End Rods, etc.)
Thankfully both Bugs that raised in this Update due to how common are getting reproduced are finally fixed after Months/Years. Kudos on Henrik for the fix of these Issues.

@Dorgami Flowerpots have been fixed in MC-96319, mobs no longer gets stuck in them nor think they can pathfind through them. The list above are the few remaining blocks in the game mobs still try to pathfind through.

Most mobs (Skeletons are the only exception as far as I know) are unable to pathfind on and/or to carpets with torches underneath.
To reproduce:
- Make a floor out of any block you can places torches on (Stone for example)
- Place torches on top of the stone
- Place carpets on top of the torches
- Spawn a few mobs on the carpets

this bug is related to
MC-134847Most likely related to path-finding as well, so I'll instead add to the issue here:
Mobs get stuck on top of half blocks, whether or not they can collide with them (this in Minecraft Java Edition, version 1.14.1 Pre-Release 2):
These foxes attempt to catch the fish underwater, but get stuck on top of the kelp or sea grass.
In this case, despite seemingly having a continuous path underneath them, the mob will spin in place in a failed attempt at finding the path to its target.
A similar issue of path-finding appears to occur with the villager getting stuck inside a space enclosed with open trapdoors. It most likely happens since it's not taking into account the new 'open' state the trapdoor is in, this since the villager is just pushing himself towards the edge of the trapdoor instead of jumping.
Vortex, your issue is
MC-136318.@violine1101
I see, I believe the filters I set to see if there was already an issue like mine were too limiting. Should I move that comment there or delete it, since the info I add is pretty much already covered there?
Still in 1.14.1 Release
(1.14.1van/Win 10/i7/16 GB)
Special for villagers concerning flower pots with cacti:
Usually, villagers will just run across any flower pot, but they get stuck at any flower pot with a cactus inside.
Still in 1.14.2 Pre-Release 1 and 1.14.2 Pre-Release 2
(1.14.2v on i7/16GB/Win10)
Can we please add trapdoors to this, or are they really meant to trap animals and villagers?
I have an entire village population (including foxes) trapped in the trapdoor decorations of their village…
Jens-Oliver Tofahrn, that's a separate issue, see
MC-50556.This issue is still in 1.14.2 and Pre-release 2 for 1.14.3
According to
MC-154430, campfires are affected as well.Was directed here from my other bug report here -
MC-156334Villager pathfinding can cause them to be stuck in various configurations when an obstacle is in the way of their 'escape' -
1 - Trap doors in an open position (single trapdoor where they stop instead of hopping over if there's enough space above), or double trapdoors - they will walk up to the double trap door and just stand there instead of path-finding around)
2- Top-side slab (1/2 block above the ground level where the villager is) with a double carpet over it. The villager will approach it and constantly jump.
3 - A double carpet at ground level - The villager will approach the carpet and just stand there.
4 - Water-logged stairs. Villagers will spin for about 10 seconds before attempting to cross. Water-logged slabs are ok.
5 - Fence block in the ground with an obstruction 3 blocks up. The villager will attempt to cross the fence, but can't, even if there is an opening.
(Interestingly enough, when I tried this with a fence gate, the villager did not choose a profession until the fence gate was opened. In all of the other tests, they chose a profession, so they saw a path as valid).
Still in 19w35a

For god sake fix this please. Still an issue in 19w46b. My village is effectively useless as all villagers get stuck on every bloody flowerpot placed on the floor, where there are two blocks headroom. See pic.
In 20w12a
A workaround for flower pots (would need some work for a survival implementation, and you have to wait till something's in the pot)
Armor stand position can be adjusted to make it work for any of these blocks that are affected.

Notes:
Can't believe that this is gonna be fixed in the next snapshot... FINALLY!!!
The fix will make all of the blocks in the description be regarded as solid, except ladders. These is a separate bug for ladder pathfinding.
The fix also makes waterlogged stairs, slabs etc be regarded as solid, not as water.
This bug is only about blocks that should be regarded as solid. I did not fix other pathfinding issues, e.g.
@ Matthew Gatland
In regards to Carpets and specially villagers and this ticket
MC-97799It first became a problem after you changed the height of Villagers in v. 1.9 from 1.8block to 1.95block, before version 1.9, Villagers had no problem walking throug doorways with carpet in front.Possible solutions:
1) Change Villagers Height back
2) Change height of carpet/change collision of carpet
3) Update the structures of Village buildings where there's carpet infront of the doorways (This is rather odd, since you knew about the bug before 1.14 yet some of the new structures, such as "snowy_masons_house_1" have carpet in their doorways rendering the building unusabel by villagers)
So I have done some testing in the latest snapshot 20w17a and found there are still a couple of blocks mobs do not regards as an obstruction.
The following blocks are affected:
See attached screenshots.
Note: I have not tested this with every mob in the game but with villagers and zombies.
They also don't regard turtle eggs as obstructions.
Oh yeah, I forgot to test those.
Shulker Entities are also not considered obstructions
This is still present in 20w18a in regards to the object I listed in my above comment.
Should I create a new ticket for these?
Yes, please. Shulker entities are not blocks and thus not really covered by this ticket.
New ticket MC-181565
