Not really seeing an option that says "Return to garrison" or such for Patrols, so I'm just selecting them to reinforce my town as a way of returning. However when they do, the units just... disappear. Gone. Tracked one of the patrols for this, and confirmed it. They didn't change the garrisoned amount. Strangely when you do this where the patrol has prisoners, the prisoners are added to the garrison as recruited units as well. Just wondering if I'm screwing this up somehow or if this is an actual bug in it?
