I bought a square ruby from the auction house, which was a buggy nightmare to begin with. I used the gem for a few hours and then traded it to a buddy who is playing 3 feet from me. Upon porting to the next zone directly out of Bastion Keep we both get DC/ED. When we reconnected immedietly the trade was not saved. We trading more than one item during that session and it took about an hour of messing around to find out that gem trading in general was causing the crash. Eventually (day later) we got it traded by dropping it on the floor.

Anyone else have any wierd issues like that?
