Dathomir - Boss Gorgara will not spawn after dying - Rocks don't fall

Happened to me to. Gorgara is nowhere to be seen while climbing  the wall. The boss music still plays while climbing and even When i reach the top of the wall the cinematic plays but there's no Gorgara. So you just see Kestis flying around the air frantically. Then the segment where you have to land on Gorgara plays without it actually being there and of course you can't land when there's nothing there so it completely halts and forward progession. Ive tried common fixes like restarting my console (xbox one) and restarting the game but to no avail. Heck of a shame too, i was absolutely having a blast with this game.
