I didn't think ahead in grabbing a screenshot/video, but I was able to replicate the bug in game before leaving the strike itself. Two Guardians were engaged with Thaviks (Exxodus Down Strike) and when I joined from Heroic Strike matchmaker I was stuck behind the "wall" that seperates the rest of the world from the Strike arena. I was able to get away from the wall and use the "Rejoining Fireteam" mechanic but it placed me behind the wall unable to join the fight. I attempted multiple times to "rejoin" but was never able to get past the wall. I assume it's happened before and I'm just re-reporting but I'll send it just in case.
