MCPE-101670Most mobs get stuck on and between damaging blocks (cactus, magma, campfire, fire)
Mobs will not path off the top of damaging blocks in many cases. They appear to view the 8 blocks surrounding a cactus, magma block, or campfire as damaging, and therefore will not path to them if they have
"avoid_damage_blocks": true
within "minecraft:navigation.walk". That means they will not leave the top of a damage block if it is elevated, unless they target something farther away than 1 block. For example, if you spawn a wolf on a cactus, magma block, or campfire, and a sheep next to the block, the wolf will get angry but will not move until the sheep begins to wander away. Moreover, the panic behavior seems to be restricted to targeting adjacent blocks, so mobs with "minecraft:behavior.panic" (e.g. llamas, chickens) will not step down from a cactus as they should because they can’t find a “safe” block.
Steps to reproduce
- Place a cactus block on sand.
- Summon a mob on top of the cactus.
Expected result
The mob moves off of the cactus because it is getting hurt!
Actual result
Most mobs will not path off of the cactus.

Confirmed for cats only, as regards teleporting.
- Pet wolves/dogs will teleport off of cactus.
- Walking off of cactus is a problem for a much larger set of mobs, so I have made MCPE-101670 for that.
What all of the mobs covered by this report have in common is a hitbox larger than one block.
@thistriagonalsign: the issues you describe with magma and campfires are covered by MCPE-101670. Those issues are not related to the mobs’ hitboxes as this one is.
Thank you for your report!

This behavior is caused by the fact that phantoms try to avoid getting within 16 blocks of cats, but they are not able to select pathfinding targets that far away, so when spawned near a cat they cannot find a block to path to.
When spawned next to a cat, phantoms move away horizontally for 5-6 blocks and then try to turn upward, but then immediately turn around. The do this even if spawned next to cat that is sitting on a pillar 20 blocks above the ground, or one suspended in the air by a repeating teleport command. The phantom turns around instead of flying up because every block they can scan above them is still within 16 blocks of the cat. It's analogous to MCPE-101670.

this happens to me a lot. Whenever I am fighting some piglins in the nether, and I lead them into a fire, they just jump around in the fire and don't even try to get out.

Still occurs in 1.17.11 Hotfix.
Another issue caused by this bug, is that mobs can get trapped between 2 damage blocks. For example, on sand place 2 cacti with a 1-2 block soace in between them, and spawn a chicken in that gap. It will never move on its own. A baby chick will not move from that spot to follow an adult, a wolf will not move from that spot to attack a sheep, etc.
These wolves want to eat the sheep but feel it’s unsafe to move away from the cactus:
