Has anyone experienced the following:

Broken quests (Glitched)

Mannequin apparel duplication glitch (Your Mannequin duplicates clothes)

Dagger Rack Glitch (can't retrieve your daggers from your dagger rack) [specifically in Hjerlem)

If so, please tell me how to deal with them

I believe it's safe to say that most of us have experienced all these, more or less.

For the PC version, the unofficial patches have solved 99.9% of them. On either Console and given that you know what glitches when, you need to be very careful...
