i'm sure it's not related to the coding itself, as the errors that people receive when attempting to enter maps (i.e. "cannot connect to front server", "bad token", etc.) are entirely related to the connection between the server and the user, and are quite separate from the coding of the map itself.
the only reason for these errors - as far as i know - is that the server's hard drives are giving out and aren't able to support connections for whatever reasons. i'm sure in due time this will be fixed, as feral heart doesn't have a warehouse full of servers like facebook does, so we will have to put our faith in the ones we do have. lol.
