[XBOX] Jun transportation mission stuck inside the crucible forge

I couldn't complete the Jun transportation mission in a map due to the mission spawning inside the crucible forge. I could see the transportation wagons but there were no associated syndicate members or guards to kill. I completed the forge in case this would resolve the issue, but no such luck.

And seeing as the attempt to paste the screenshot failed, here's a link to its location:
