Trying to solo the Grandmaster version of the strike, and this has happened three times now. I get to the part where the Drake sometimes spawns, and the quest marker won't move or update. If I go forward to where you need to kill the two miniboss Cabal to activate the cannon things to get onto the drill, nothing spawns. Video shows where the marker gets stuck at, I've tried going backwards to see if I missed a load zone, and tried clearing all the ads even the ones that aren't normally necessary to progress, and nothing works. I've seen two videos on youtube with people having the same problem a couple months ago, but haven't found any solutions. Is the strike entirely broken right now? Or have I just been super unlucky?
