Villagers and mobs try to pathfind through corners
The bug
Mobs try to pathfind through corners, if there is an air block behind the corner. This seems to affect all mobs, including passive mobs such as villagers.
To reproduce
- Build a diagonal wall that mobs could theoretically walk around
- Behind that wall, build a pillar
- Climb on that pillar
- Switch to Survival mode
- Spawn a zombie on the other side of the wall

Sorry, I am creating this bug again because MC-142516 was resolved as a duplicate of a non-related bug.
"Zombies, Creepers, Skeletons are all behaving like they have no AI for pathfinding at all. In bamboo forests or inside mineshafts they are unable to get around a corner (or double corner), just to reach me. Instead they are searching for the shortest direct path and get stuck."
All mobs are generally moving and are following me. They have also seen me, I usually hit them first and run just 5 blocks away. All the mobs in the picture have seen me, followed, but then stayed where you can see them. They just have no clue how to get around.

Thanks for your testing. However I doubt that this is the single cause of the issue, there are other issues at play here as well, see MC-142817 for example.
I've resolved this ticket as Invalid as this is technically not a bug report.

This bug has already been reported, see MC-142817. It will be fixed in 1.14.1!

Tarkunbiur, that issue is MC-142817 and should be fixed as of 1.14.1-pre1.

After some digging, I can confirm this issue was actually fixed in 1.14.1 Pre-Release 1. Specifically; check out MC-142817 for the issue.
Zombies can still remember entities through corners only if the corner is placed after the zombie locks on to the target. But, this also applies to blocks placed in a vertical/horizontal row.
With that being said, all the versions after 1.14.1 pre-release 1 seem to be another issue, which is that mobs can remember entities after they no longer have line of sight to them.
1.14 vs. 1.14.1 pre-release 1

I added some more pictures of mobs not following anymore if they reach bamboo.
If I remember correctly, this is a feature of the AI appearing when it's not supposed to. Ordinarily, when the AI cannot create a path from the monster to its target, it will attempt to simply get as close as possible without entering a hazard. However, in these cases, the monster clearly has a very short path to follow but is prevented from following the path. This definitely relates to my
MC-142964, except manifesting in a comically more severe way. In fact let me test this...Well, part of your error is something more obvious - mobs path through Bamboo like they would tall grass; they ignore it entirely.
Confirmed in 19w12b. I edited the ticket a bit (I hope you're fine with that, OP) and attached a video showcasing this bug.
This behaviour can also be observed with villagers in snowy tundra villages. They try to get in and out of their igloos by going through their corners.
Still in 19w13a
This happens very, very frequently in Savanna Villages, since most the Houses are based with no Corners Villagers gets stuck there trying to reach their Beds even if the Door is close to them.
Still in 19w14a
Still in 19w14b and 1.14 Pre-Release 1
Still in 1.14 Pre-Release 2
Added images of Savanna villagers when they walk around corners and they begin to jump up and down. They eventually stop but some have stayed out at night not able to reach their beds.
Villagers leave their village never to return. I watched a villager wander off from a taiga village; I followed him for 400 blocks as he walked purposefully away from everyone and everything he knew. Last I saw him he was headed for a bamboo forest

My comment was marked resolved as a duplicate of this ticket, but I don't see any comments relating specifically to my issue so I am copying my comment from the other ticket to here.
The issue you're describing is entirely unrelated to this ticket. Please create a new report.
Still in 1.14 pre-3, 1.14 pre-4 and 1.14 pre-5
Still in 1.14 Release
Yes, the problem still prevails in the latest 1.14 release:

Imagine a new player on a wooden home hidden on a corner of his house...
And them his entire house explodes and he dies, not understanding anything that happened he questions to himself: "why did my house explode"
Confirmed (esp. for cats + villagers) in 1.14 official. They also try to jump onto 1.5 block high structures, like block+slab fences
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-96319gets squashed too, it's another Bug that can be reproduced more commonly in this Update.I wonder if this solves other pathfinding issues for villagers. In particular I have noticed, trying to pathfind under trap doors (making a less than two block high space), trying to pathfind over carpets in a two block high space (villagers are too tall), pathfinding to the nearest wall or roof to their workstation, even when a perfectly acceptable path to the workstation exists, pathfinding to glass panes or walls instead of to doors, climbing ladders and getting stuck at the top on a closed trapdoor (and not leaving). And those are just what I've noticed in the past few days.
I also hope this fix indirectly the obstruction issue that happens in Villagers and of course in other Mobs where they don't count Bamboo, Lanterns and Flower Pots as obstructions, making them try to Pathfind directly through these Blocks resulting in see Mobs often get stuck instead of Pathfind around these Blocks.
I found this when I tried to make a Jungle Village close to a Bamboo Forest and when the Villagers started the "Wander" Schedule they often get stuck around the Bamboo (Most of the times is just 1 Bamboo in front of them what causes the problem), same for Golems, Zombies or any kind of Mob and since I noticed the Reporter of this Issue added a Picture with Bamboo so it might be a double Fix (Hopefully).
Villagers and of course in other Mobs where they don't count Bamboo, Lanterns and Flower Pots as obstructions
Same thing to fences.
MC-147905MC-96319is 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.
Why is this resolved? I have a similar issue on 1.11.4 Bedrock for Nintendo Switch. I’ve seen villagers not being able to reach workstations and beds even when they are on the other side of the door between them. It’s almost as if they don’t know how to use the door half of the time unless it’s open. Villagers end up staying outside at night or run directly into zombies. It’s very annoying because I often see villagers hanging around the overhang of the roof or walking back and forth outside to get to the bed from outside instead of using the door.
Fixed for Java Edition.
It’s an issue in bedrock Edition too. Villager path finding is awful. Forget about building two story buildings because Villagers can barely find themselves in a house. They also don’t respond to the bell sometimes. I don’t know if I should create a separate report because there are several issues. I sometimes wish that they never change the formula from doors to beds.
This section of the bug tracker is for Java Edition only. For Bedrock Edition, please visit the MCPE project.
This bug is back again in 19w36a, but may be only when doing certain AI tasks. I've seen a villager path-find into a pair of diagonal fence posts while heading to work. but seem to avoid doing so when doing other things.
Tyler Purcell, if so, please create a new ticket (and link to this ticket in the description).
Sorry about that. Though, the bug seems to be different this time around so I've created a ticket for a "different" bug; one regarding villagers path-finding to work (and possibly other targets as well). Because this time around it might just be them path-finding straight to the target as opposed to path-finding thru corners.
