Cradle of Sulevin Quest glitch

I did the same thing he did and have the same problem, no reloading doesn't work, restarting doesn't work, changing areas doesnt work or zones

Did anyone ever figure this out?

My problem occurs when I turn in the quest. Did the whole level, then farmed for schematics for about an hour. Go turn it in to Dagna and the save option locks up in the menu. After about 10 mins or so, the game crashes and I don't have anything I did during that time.

I tested it by loading an old save and then saving right before I talk to dagna. The save option locks up right after the conversation is completed, when the rewards are being given. If I don't turn the quest in, everything is working fine, only when I turn the quest in is when the issue occurs. Am I the only one experiencing this issue?

EDIT: Solution if issues occur after you turn it in: fast travel to Val Royeaux, I didn't attempt any other location, only Val so other places may work as wel.

I went back to an old save before I even did the mission, a little over 3 hours of pure schematic and resource farming with some weapon and armor crafting, and i started the mission over. I turned it in and the same issue occured, save button locked up. As I waited for the game to crash again and send another report, I decided to travel to Val Royeaux and see if there was anything I could buy. When the screen reloaded and I was in Val Royeaux, the autosave icon appeared and I checked and sure enough, the save option was no longer locked and the weapon was in my inventory. So I loaded up the save I had after my farming and tried to turn in the mission again (I was mad after the first couple of tries, so I saved before turning the quest in and went and farmed). Turned the quest in, sure enough same issue with the save option locking. So I traveled to Val Royeaux and like clock work, the same results occured, autosave icon loads and I check and everything is working.

I can only guess that the fast travel didn't work because I only traveled to the emerald graves and maybe that wasn't far enough away? I don't remember anything about needing to go to Val either.

Same PROBLEM, tried all the logical fixes, I can't get the 4th piece after running my dead butt out the first time. Mine was the lower chamber revenant I missed
