Mobs spin while pathfinding in 1.14.4

[thehc]

Starting in forge version 1.14.4-28.1.72 I've notices that mobs will spin while trying to path find. This includes sheep following the player or zombies tracking the player. I've checked versions 28.1.71 and 28.1.111 (latest) to confirm the behavior is still present. I did all of my testing with no mods installed (besides forge).

 

Expected Behavior:

Mobs that are path finding (sheep following wheat or zombies tracking a player, etc.) should move towards the player in a mostly straight line.

 

Actual Behavior:

Starting in version 28.1.72, mobs will randomly spin 360 degrees every few seconds. They mostly don't spin all together. This behavior is more frequent when the player is moving.

 

Tested versions:

28.1.0 - good

28.1.70 - good

28.1.71 - good

28.1.72 - spinning

28.1.73 - spinning

28.1.111 (latest) - spinning

This problem could be one of many:

1. There could be an unending loop of checks to follow the player or not, some of them being don't follow.

2. The navmesh or anything that the entities use to path find could be broken.

3. Something could be preventing the entities from following the player, hence the spinning. (re-calculation)

 

These are what popped into my head, but I'm not a developer. The only thing we can do is wait for the fix. (Although maybe leads can work? There's no pathfinding with leads so it probably will.)

This is still happening even in the latest forge for 1.15.1. it's really annoying because at times it completely breaks the game...Mobs attack retardedly and they aren't really a challenge anymore which is game-breaking.

Please provide more details, as this is not reproducible in our test environments, and actually 28.1.72 specifically FIXED mobs spinning in circles when they ended their navigation.

I've experienced this with the latest 1.15.1 build while I was tinkering with making custom mobs, so I went back and used the latest forge without any mods, and compared it to vanilla.

 

I ran vanilla, spawned some cows from eggs in creative mode, flew in the air, and watched them wander around for a few.

Did the same with a fresh forge world ( 1.15.1 - 30.0.41 ), and the cows were noticably spinning circles here and there, without any real reason that I could discern, and I did not see that happen with the vanilla cows.

 

Let me know if I can provide you logs or video of it happening, I'd be happy to help any way I can, even if it's to get a working as intended

typoed mobs when i meant mods

Same here, I thought I was all the mods I had added so I removed them all and tested on forge with no mods and the cows and such would spin sometimes while pathfinding.
