I did the Gjallarhorn quests, got it, fused it with the Iron Gjallarhorn. I used it, finished leveling it and increased the light level to 350. When I logged in today, I could not use it anymore. It's still at light level 350, but it says "requires year 3 Gjallarhorn" again. Any ideas how I can get my Iron Gjallarhorn working again? :/ Edit: just noticed all my pre order items are disabled
