So I got some new pants today (Leggings of Woven Death) and I slapped 3 23SP gems in them because I was about to raid and didn't have time to track down proper gems. Anyways, so I go and get the proper gems, one blue, one yellow, one red. As I replace the gems, I notice that it's letting me replace the gems while giving me the gem that's currently in the leggings, so 2 of the gems I replace are not deleted, I put them on the AH right after and came out 460g richer.
Has this happened to anyone else?
