Having a different bug than any i've found. After talking to daniel, telling him that all the work in the Valley is done and you've found the map of the grand staircase, then siding with Joshua, Vegas teleports you to Joshua outside of the Narrows. Joshua won't talk, and the player is stuck in a cutscene. Nothing happens. I enable player controls, try to talk to him, and no new topics. I tried using setstage to skip over this, but still nothing changes. I then tried siding with Daniel, but it still teleports you to Joshua, and he still says nothing.
