--- Comment #14 from Joaquín Tumas j.tumas@gmail.com 2011-08-28 22:27:25 CDT --- As this game only lets you play with the last version, I think this bug should be set as fixed, as nobody could repeat the error conditions even if it was a game update. Any way, I had the error with older wine version and it was gone with the newer, so it probably was fixed by wine devs.
FYI: with ACE client the game is not longer working OK right now (can't join a match)
