...I noticed that i'm suddenly being hit with all sorts of bugs, mainly quest related. 1. collect bounty from skald, I've collected the bounty but the task remains in misc section. 2.The rescue, I went home and my wife starts asking me for help, then I start a quest called the rescue, yet my wife is still at home acting normal. 3. I go into a cave and free this dark elf selvani and it tells me to help her escape, now she's stuck at the cave enterance and too far away to talk too and the quest won't complete. All these are stuck in my journal, unable to complete, does anyone know how to finish these or remove them from the journal? i'm on xbox 360 so no console commands.

2. Check the Bugs section in http://www.uesp.net/wiki/Skyrim:Rescue.

3. Try Unrelenting Force.

Those are all known quest bugs. Nope, nothing you can do about it. Sorry.

Actually I remember pushing the dark elf lady out of the cave somehow... Though I must have entered and exited the cave more than 20 times to manage it on Xbox.
It's doable, just teeth-grinding beyond reason.
