Still happening in 1.8. One of my important pre-1.8 villager just died from a cactus.

Roy Sajima 2016-06-03T07:56:07Z

Confirmed for 1.1, and also for magma blocks.

Elemend 2018-08-02T22:05:14Z

Affects 18w49a. Also berry bushes should be added to the list.

As of 19w02a, campfires seem to be affected as well, see MC-142066

Michał 2019-02-24T23:06:12Z

However mobs that die because of the campfire should drop cooked meat

Cat killed itself. Was sad

user-2a4c8 2020-04-15T21:01:15Z

Glad I found this. My dog almost died while I was building, had to push it off the campfire because it just stood there.

David Harmon 2020-05-04T03:36:55Z

Still in 20w17 at least:

Took a couple of dogs caving with me... one of them tried to swim up a falling lava stream, after I'd already quenched the base – there was plenty of room. "Dog tried to swim in lava" – yep, they sure did! The other wandered across the corner of a half-quenched lava pool, and burned to death, and had no obvious reason to want to go down that corridor.

Orbic 2020-06-10T20:20:20Z

Related, and possibly the same bug. I noticed that when standing on magma blocks, mobs make no effort to get off of them even when they easily can, just stand there taking damage until they either die or they randomly wander off. Just like the villager on that cactus in the pic. Tested this in 1.16 Pre 3

Jeanne Richard 2020-07-17T18:19:38Z

😞 Yeah, still an issue. Had a parrot suicide on a berry bush outside of my house because they decided it was a great place to settle down to rest.

Can confirm in 1.21.3

Shugoh 2024-11-11T13:01:22Z

@unknown Do you have any reproduction steps you could supply for this issue, since you just confirmed it?

Minecraft386882 2024-11-11T14:30:01Z

Place a magma block 3 blocks in front of the player and 4 more blocks (2 extending left and right each), then lure a villager with food.

Observed result: The villager takes damage from the magma block.

Expected results: The villager can path find around the magma blocks to go towards the player.

Also speaking about villagers, I want to highlight a few other serious bugs:

*Particularly important

Lyoneer 2024-11-12T12:33:58Z

The villagers pathfind around the magma for me, and doesn't take damage. If I close the food in with magma blocks they will just stare at it. Do you have any other reproducing steps?

Shawn82 2024-11-12T12:45:52Z

I can't reproduce this in 1.21.3 and 24w45a either. Attached the image.

Lyoneer 2024-11-13T11:40:43Z

Closing this ticket as cannot reproduce.
