Okay fellas my problem is that I sometimes go exploring off track for no reason and I will enter a place like a cave for example, right? So I go into the place and I find an item like Rjorn's Drum so I pick it up. Later on I then find the quest for the drum to go get the drum. So I talk to the quest giver and choose one of the speech lines you can pick, right? Okay and I pick one line which then gives me the quest in my Misc. quests. Then I tell the quest giver that I have the drum. He says w.e blah blah you found it... It stays in my inventory. The item it does not disapear and leave like I cannot give it to him. I keep trying to buy selecting 'I found the drum' line and he just keeps saying the same b.s. all over again and again heh. Soooo, can someone please help me out here please and ty? I have multiple quest items I guess just like this. please someone help!!

this happened to me as well, they need to patch it to fix it. I have quite a few quest items stuck in my inventory. Only solution is console commands or load a previous save before picking up the item and starting the quest normally.

It is a bug. It will probably be addressed in the upcoming data patch.

However, while they are cluttering up your inventory, their weight does not count towards your encumbrance.

Also, it does not matter when you get the drum (before you get the quest or after) it stays in your inventory.

i try not to pick up things that have a quest-item name, like "this guys" "stupid thing". Learnt that the hard way though.
