Minecolonies version

Version: minecolonies-1.12.2-0.10.43-ALPHA-universal

Expected behavior

The miner stays down in the mine and mines

Actual behaviour

The miner is unable to path correctly, caused by the mod Improved Mobs, and thus gets stuck cycling through all posible states it can be in.

Steps to reproduce the problem

1. Have Minecolonies
2. Have the mod Improved Mobs https://minecraft.curseforge.com/projects/improved-mobs
3. Observe the miner getting freaked out.

Is this caused by the amount of mobs down in the mines?

This also happened on passive - without any hostile mobs present. I think the mod itself taints the pathfinding, because it allows certain mobs to break blocks to reach their destination.

That's weird, but does it influence other mobs? Does it add any special blocks?

No blocks added if I recall - but it alters pathfinding for zombies I think, and several other mobs. I've had it disabled for a while, so I would need to test it out again to find out exactly what it did.

All I know is that when I enabled the mod, the miner got confused.

Okay, I just checked her code and it seems like she overrides all existing pathfinders for this.
Basically killing mod compatibility.
That would have to be fixed on her side, we can't do anything here.

That explains it. Thanks for checking it out.
