Xbox 360
Level 60

One of my favorite things to do is collect unique/rare weapons/items and display them in my character's houses. On this play through, I wasn't able to acquire Trollsbane (NPC wasn't in the cave to loot...tried leaving the cell, waiting 31 game days and returning, but he still wasn't there) or Valdr's Lucky Dagger (apparently, I found Valdr at too high a level, so he's healed enough to not initiate the quest).

I found out after the fact that both of those are well enough known glitches.

Trollsbane I can live without, but I'm disappointed enough with not getting Valdr's Lucky Dagger to consider starting over...I'd also like to get the Nightengale Blade at a lower level when it's still smithable and avoid dropping the Sapphire Dragon Claw when it's no longer a quest item only to pick it back up to find out it is a quest item again and undroppable.

So are there any other glitches you know of I should watch out for as I go through and start collecting again? I do know of the one with Ahtar's Headsman Axe, but I was able to reload an old save to get it.

Better yet, have you had any success working around the glitches with Trollsbane or Valdr's Lucky Dagger on the 360?
