Summary

0010186: Dwarf in an infinite loop

Description

I'd been having problems with dwarves stuck in trees, so I built stairs next to some of the trees so they could get down and disabled picking fruit. This one poor herbalist is climbing a ladder and going down the stairs over and over again, I've tried marking the ladder to be dumped and nothing happens (though that's probably a good thing)! When I remove the stairs, he climbs the tree one more time, cancels Gather Plants: Could not find path and stays up there.

When the task is taken up again, it's done in a working fashion. Using vanilla a civilian alert will also cause the gatherer (and everyone else) to break their activities, although a civilian alert burrow can be set to just exclude the tree to only affect the intended target (a regular burrow is ignored by the gatherer until the task is complete, which it never is). My guess is that the tree grew after the gatherer set out to gather fruit, resulting in the original path being broken, and the gatherer trying to continue using the now broken path, rather than computing a new one.
