bad token has moslty nothing to do with your map on his own, but with the connection from their server with the FH server.
sometimes when there are already a lot of people their, or many objects or when the player just has a weak connection, it can be difficult to make a connection with the map server, which result in bad token.
moslty, when you relog-in, it shoul be fixed. sometimes it can happen a second time ...
but moslty you only get one bad token.
I also have i with one of my own maps, possible because there are a lot of re-textured things in there, so a lot of stuff to load ... which makes your connection weak
