so, i've place 3 items in a large glass display case the archmage's robes, savos aren's amulet, and the wooden mask. i then left the house i had built and continued to quest on. but when i came back i had noticed the amulet and robes were on top of the display case and the wooden mask was completely gone. i tried shouting to possibly discover the where abouts of the mask but nothing. anyway to fix this or possibly recover sed lost mask?
