There doesn't seem to be any way of checking which levels I already completed when selecting a level -- and the completed level tracker under achievements is definitely off...
Alas, saved games seem to be corrupted for me -- they load, but after loading a saved game I start walking through doors without the insides of housing displaying. :(
After the server "upgrade", the came has become absolutely impossible to use -- I am constantly waiting for server connections, and, if I have the luck and patience to get through a day (which may take 20 minutes after all of the delays), I am more than likely to have to restart it anyway (error #...)
