My thoughts on a simple quick fix (until each quest can be sorted out) is to simply make ALL quests items weigh zero pounds this would at least allow people to move on to other things without worrying about quest items weighing them down
thnx.......
Same issue here. Found the drum before doing any Bard College quests. I did get the skill rewards from Giraud, but he doesn't take the drum, and I can continue to go through the dialog options trying to give it to him. I also want to point out that I gave him the drum before doing the main Bard College quest "Tending the Flames", and this seems to have glitched that quest reward as well. I got the gold after watching the festival, but not the "Gift of the Gab" perk. I was able to do the Lute and Flute retrieval quests and get rewarded without issue (apparently). Edit: just noticed the lute and flute did not leave my inventory either.
Other glitches so far: random dragon kill didn't result in absorbed dragon soul. Corpse is lootable, but never turned into a skeleton.
Southfringe Sanctum cave quest, help Selveni Nethri escape: She doesn't actually leave the cave. She is standing at the entrance of the cave (from the inside), but beyond the range of communicating with her. She apparently doesn't actually leave, and the quest never shows as complete. I can hit her with magic or a bow and kill her, but the quest doesn't update. I killed all of the cave inhabitants before cutting her down and talking to her, then I just followed her to the exit.
I am not able to get the "Lovers Comfort" temp perk when sleeping at home I share with my wife. I married Camilla from Riverwood, and we are living in Breezehome in Whiterun. When ever I sleep here, I only get the Well Rested temp perk. The only dialog options I have with the wife are: asking for gold from the shop, buying/selling, asking for a meal, and moving someplace else.
Not sure about this one, but I have two Alik'r warriors just camping out at the entrance to Whiterun after doing the quest for Saadia "In my time of need" quest. I got the dialog from her in the inn where she pulls a dagger, but instead of going to the prison to find the location of the guys after her, I went to the cave and killed them all while doing another quest in the same cave. When I speak to either of the two guys buy the door, all they say is "What do you need?". Maybe they are there for another quest, but they weren't there before rampaging through that cave for the quest, and they never move.
