ok, that's a weird one, I came to the druid grove and the goblin fight started.
I just continued walking the road towards blighted village and, once well outside the boundaries of the fight, I picked the flee option (for the first time I think so I didn't know what to expect).
as soon as the flee was confirmed, the dialog with gale which is on the opposite side of the map started. once the dialog ended, I was in front of gale waypoint.
I made my way back to the gate, the goblins were dead and the guy from aradin's group was dead. I continued forward to the village, "inspected" the rest of aradin's group and when I came back to the grove, zevlor was standing in the middle of the way and I couldn't interact with him. once I made a round trip inside the grove, everything returned to normal...
is it how the "flee" button in meant to work ?
