Summary0000891: New HFS pathing troubles; ends up in a pathing "freeze"
DescriptionThis post will contain necessary spoilers.

I recently breached "hell" and had a whole slew of demons fly up to kill me and my fort. That was cool and all...until I had only two dwarves left. Every demon decided to path towards a sleeping dwarf. They were forced down a single tile wide hallway, and it seemed that all but 2 of the demons ended up "stuck" in the hallway, as if they were all waiting for the other to move out of the way.

The dwarf eventually died, but the demons remaiend stuck in the hallway despite another dwarf living in a different part of the fort. The demons are still stuck.

After observing them it appears that they're stuck in some sort of "making room" loop. After room is made (you can see a demon dart into a doorway for a split second), it seems that same demon then moves into a spot that is freed. As such they're stuck forever.

Saving and reloading did NOT fix this problem
Additional InformationThere is absolutely nothing preventing their pathing to the last dwarf in the fort. Indeed, several dead dwarves are on the same level as him.

I suspect it has to do with their flier tag?

Problem still occurs in .03, which is a shame. I was hoping to have a proper end to that fort :(

This may be related to an old bug:

Save is no longer available. If you have a save that demonstrates this problem in the latest version, please upload it to [^] and reopen this report (or PM me on the forums).
