BTW, if you've heard about the bug that makes you lose all of your cards, I heard (in some discussion regarding this) that it was related to Chrome. I wouldn't want to lose my progresses, so I switched to Firefox for playing elements only. If what Rutarete linked works, I'll go back at it.
Has someone else tried it?
I heard about that happening to
one person. It was related to chrome in the sense that I think that person was using chrome and it happened around the time when the chrome problems started happening. In the thread about it, zanz mentioned that some bad data had been passed to the server from the account and implied that it seemed related to some sort of hacking attempt gone bad. I see no reason to believe that the chrome bug had the tiniest bit of anything at all to do with that.
edit:
Citation. The person in question was not actually even using chrome at the time (since he says in the OP that he tried switching to chrome after the bug happened).
edit2: I don't know exactly where the discussion was that mentioned that it might have been related to chrome (though I also remember reading that at some point). When the chrome bug first started happening, "maybe it's chrome's fault" became an answer to just about every new weird thing that was happening with the game for a bit, though. Either way, I'm not losing any sleep worrying about this one.
