Hi I noticed just last night that my allagan legs/boots/gloves for my Monk are missing from my armory chest. I have heard of people having items missing since patch 2.3 but Monk is not my main so I didn't notice until now. They gear is not in my retainer, theres no way I discarded it, and allagan gear cannot be traded for seals. It has simply vanished.
