Issue Description

I haven't tested with every slabs in Minecraft, but it seems that succubus mob AI has trouble walking on slabs placed by players.
I encountered this bug completely by accident, my nether base floor is made out of Polished Blackstone Slabs to prevent nether mobs from spawning in my base.
I lure some Succubus back to my base and found that they're all frozen in place. Spawned some succubus at a single spot, can confirm their AI can not do pathfinding at all.

Do you have any performance mods installed that might be messing with their AI?

Unable to reproduce the issue
Not "Polished Deepslate Brick Slabs", the "Polished Blackstone Slabs".

Shouldn't matter what slabs are used

Here's what I found, when there's certain amounts of slabs around, their pathfinding AI broke. (both male and female)

I don't do any custom pathing, all pathing is done using vanilla AI goals, so there's no reason only Gaia mobs should break on them

I really don't know the reason, other vanilla mobs(endermen, skeletons, creepers, nether mobs) move around just fine...
I'll remove all my mods except this to check if the issue persist.

In the next version I'll re-arange the AI goal priorities maybe it's something to do with the priority

Just removed all my mods except for this one, created a super flat world, used fill command to generate a large amount of slabs, scattered some succubus on the surface, watched for 20 minutes, can confirm that none is walking.

I'll look into it
