Story Quest (LV 80) weird problem O.o

Ok guys
So basically i start (probably) the last part of story quest for neptune arch witch when you basically take control of Andromeda...now, when all the saints go for the columns, andromeda is stuck there and no matter where i go there are all these water walls, and on my quest mark there's nothing o.O on top of it unless i get out of the game, i cant get out of that story quest either D:
Does anybody have this issue as well???
