Live with it. Some people such as myself are still stuck on DLing the new client/patching. Have some gratitude for the work that Aga and others have been doing the past few months before criticising. They wasted 1 hour of yours - that's probably 1/200 of the time they've spent making this patch.
We found a game breaking bug and Roll back was the only way since some people abused it too much.
and what about my gold? GOLD I WASTED ON CARDS? WHERE IS THE ROLLBACK ON THAT?
You sure it was only 200?
