aaaand, back again XD
i had the problem yesterday as well, but after i tried it with different wolves, i thought it was a one-time thing and deleted the thread. obviously, it wasn't a one time thing at all cause i now have the same problem again.
while hunting, i select the wolves and let them hunt. usually, the selected wolves will be deleted from the "selection" page once they're busy. Now, there exactly is the problem.
i could select wolves that are obviously hunting. when trying to send them away, i got a message that they're hunting.
the wolf was in the quest treasure chest, lvl 2 selected.
(I had it several times with other wolves as well. Q: Cat Burglars lvl 2, Patience is key lvl 2)
I'm using the newest Firefox Browser on Computer.
If it isn't a bug because the wolves shouldn't vanish from the selection page, feel free to put this thread into the suggestion forum instead =D cause we really need to not see the wolves that are busy!
Edit: i have the same Problem on mobile Android with Chrome browser as well. Without changing Tabs.
