Saw that T74051 was closed as "Unable To Duplicate". I have included a saved game:
I am inside the village while the rest of the team is outside. I moved into the building before being ordered to. When the order came, I did another sweep, but the team remained outside. The task never went to "completed" and the team stayed on the road.
Reloaded (with the included saved game) and moved away from the buildings, and went in when the order came. This time the task was completed.
Is there a trigger when I "enter" the village, that is not activated since I am already inside the village when the order comes?
