Can be reproduced with a surface of glass or slabs as in the attachments from today - they will not try to avoid the fungus at all

Please split into separate bugs with specific titles.

I cannot repro the slab one. Please verify if it is an issue in the latest snapshot.

I'm no longer able to reproduce this in the setup that I originally discovered the bug in. This probably has been fixed along with the "mobs sometimes spin around while pathfinding" issue.
