I've been trying to get through the mission "Frozen," but I can't progress past the fight with the Mogai heavy warbird. I approach the Reman scout, the Mogai appears and attacks me, and then the Reman disappears during the fight. After destroying the Mogai, the mission objective changes back to "Follow Reman Scout," but the scout isn't there and there are no objective markers.
I've tried restarting the client and dropping and restarting the mission, but it always gets stuck at that exact point. I opened ticket #5,600 for this.
