Miscellaneous: HS and Seb Key disappearing from inventory.

[seekerof]

I logged on a couple weeks ago and attempted to enter seb and found that my keys were missing from inventory. I know that typically when you die they appear in your inventory after death and i died outside of seb in order to try to reobtain those keys with no success. I was wondering if there was a bug or if i need to redo the keying quests?
