I've had the Dwarven Gauntlets and Platemail in my locker ever since I unlocked them. When I logged in today to play, the Gauntlets had become a Spoon (which I've never ever picked up) and the Platemail had become Pendant of Mana (which I rarely pick up, and hadn't in last few games). No clue why the items suddenly changed, assuming this is not normal as no text pop-up signified a story based reason for this.
Given how rare Dwarven Gauntlets are to come by, I'm rather annoyed. Is there no way to fix this?
 Minutes after posting this, I played another round and cleared a dungeon. Came back to the lockers and my second and third item slots were now empty, and I hadn't used either of them in a while. One being my Crystal Ball, which was a quest reward and doesn't seem obtainable anymore. This is a pretty infuriating bug, and has stopped me playing until it's resolved.
