Dismissed hirelings not returing properly

[PALU]

I've copied a save (so it's available if of interest) where my character has encountered "a reemiläis peasant" out in the wild and zoomed in. I'm quite sure the group of people seen to the SE are part of an earlier robber quest posse (the rest are probably just outside the visible area).
The group moves away to the SE (I've move two steps towards them and they move away at the same rate). I've encountered this behavior before, including refusals to be hired until "X" has returned, where "X" wasn't killed, but simply did not return after being dismissed.
I'm not sure of which hireling group this is, as I can't keep track of them, but it doesn't have to be the latest one (but it can be).
Obviously, the buggers should have returned home a long time ago...

I've had this happen multiple times as well. I never keep hirelings around until they leave anymore; I always return to their village and dismiss them there once they say they have a day left. Hopefully this gets fixed soon; I'd like to not have to dismiss them early but unfortunately it's the only way to guarantee they won't get lost.
