--- Comment #18 from Manuel mail+wine@m-reimer.de --- I don't get any error window. Also no crash dump in "Temp". The game just does not start. Client disappears for a few seconds and then reappears with the "Reconnect" button.
So maybe a different error but I can't debug this. I guess I'll just stick with Wine 5.6 then.
