okay so I just finished the College of Winterhold Quests just after I went to Labyrinthian and picked up the Dragon Priest wooden mask that was laying on the ground in the time traveling hut that seems to do nothing really...but anyways so I was unloading a bunch of equipment in my new Archmage's Quarters and I decided to put the mask into one of the display cases then I shut the case and then continued on my marry adventures...soon my inventory was full so I journeyed back to unload some gear when I happened to look down in the case and the case was closed and empty?!?!?! Did the thieves guild decide to just steal that one item from me? Did the Dark Brotherhood assassin's take it as proof that they killed me because they were tired of being killed by me and just wanted the contract to be over with? or was it just another crappy glitch that plagues the game? any one else having items disappear on them?
oh and does anyone know if I need that mask to complete the dragon priest mask quest??
Sorry forgot to say this is the PS3 version.
