0011418: Endless pathing errors attempting to eat inaccessible food
If you have monster slayers in your fort, they will constantly cancel their task due to being "unable to find path".

errorlog.txt looks something like follows:

path fail: dwarf,Eat,177,6,169 -> 14,158,84: Id 0002573:Path Goal Start Eat Job:Station Mill Building at 176,8,169

...times like a million

1. Have a monster slayer visit
2. Allow them residency
3. Have them go into the caverns and eventually get hungry
4. Ye olde message spam
Curiously, thus far this only seems to apply to the "eat" job...

This fort was also a reclamation - I did not have this issue when i first played this fort before abandoning it.

My conclusion is that they're trying to path to food in undiscovered area.
No tags attached.

EDIT: Strangely enough, one of my marksdwarves is in the tavern, which has food contained within it, thus further confounding this mystery (unless dwarves don't take proximity into account for eating/drinking)

Is a save available, perchance?

Sadly, I already expelled the affected mercenaries, and didn't think of making a save at the time.

It's likely they were specifically targeting a preferred food that is only available somewhere inaccessible. The game doesn't exclude unrevealed tiles when creating jobs, but does exclude them when pathing to perform the jobs (0002869). You can "bulk forbid" over the unrevealed areas to make unrevealed objects unavailable.
