SPOILERS: Read at your own risk.

So I got the quest Death Brand and after you loot all the treasure from the first room I entered the second (DeathBrands Tomb). And the first time I attemped this it was fine, I picked up the sword and well i pretty much got ass handed to me. So I spawned at my last save which was right at the door to DeathBrands Tomb. As I entered for the second time I went to go pick up the sword to continue the quest but as I went to pick it up nothing appeared. When I scroll over sword its as if its not even there. I even tried to Fus Ro Dah it but nothing happened, it wouldn't budge. I already tried reloading my last save and its not working so any other suggestions or tips on how to fix this bug will be greatly appreciated, Thanks.

The sword is trolling you!

Perhaps restarting the console and clear the game cache as you start the game up, then try loading your save.

I wish they had made them look unique
