I think my entire mission is bugged. Found the entrance for the next level, but the mission doesn't update. My waypoint is still showing inside of cave 1 on the map, it doesn't appear at all on the overlay. I even watched a tutorial on youtube to see if maybe I had missed something, but no. I don't know what to do and really don't want to restart

Edit: Just restarted with a new character and it hasn't bugged this time around, still think this shouldn't happen though. So if it can be fixed for other players that would great?
