I need help really bad, Iv'e looked all over the place and haven't found anything that could help me. I am currently playing dawnguard on pc and i am on the final step of the quest which is "enter the soul cairn". I am able to get into the soul cairn just fine but the game doesn't check off the "enter soul cairn" part of chasing echoes and therefore it does not complete the quest and i can no longer initiate conversation with serana all she says is "lets go. my mother must be waiting on the other side of that thing" and that is it. i cant get trade equipment, tell her to wait here, or any other dialogue options. and even when i put in the complete quest console command still nothing from serana and the "enter the soul cairn" part of the quest still isnt checked off even though it is in the list of completed quests. please please please help i would really really appreciate it!!!!!
