Suddenly can't equip my weapon
When I logged on today I noticed that my weapon wasn't equipped and it also wasn't in my inventory so I freaked out a bit but later noticed that I had gotten mail. When I checked my mail I had a message from the server saying that there was an issue with equipping my weapon and my weapon had been sent to myself via mail. I tried equipping it again and it just keeps saying that the item cannot be equipped.
The item in question is: Smoldering Claw (polearm) and my class is a Warrior. I have used this weapon since like level 50 (I am now 61) without any issues.
