When I fill my dragon market, I receive 1 gem. Unfortunately this currency is bugged. The game steals it if I log off, and crashes if I try to spend it.

I figured out where the gems went. The game doesn't recognize the dragon market gems as valid currency. It steals them from me when I log out and crashes me if I try to spend it.

I am the leader of an alliance and I've already lost one member due to their gems disappearing when they relogged. I have another member that's talking about quitting. She lost over 400 gems. Personally. whenever I log off I lose gems as well so I try to spend them before I log off. I don't know if this problem is widespread or if it's only happening happening to my alliance but until this problem is resolved I'm afraid that I will keep losing members and I am personally scared to spend any more money on gems till this issue is resolved.
