There are a bunch of game available to join, but they all say unknown map. I asked one of the guys who posted those challenges, and he said he did not use non-standard maps.

So, is this a bug? It seems like one, because I don't think there are any non-standard maps yet, but the lobby says they are unknown maps.

unless there's different versions of the game, like steam or patch levels maybe?

This means that both of you have a different file set. You should reinstall your game, or the other guy.

How could we have a different fileset? We are currently playing a multiplayer game. But, other games this same person has set up say they are a non-standard map.

There is only one version of this game so far, so how can we have a different fileset?

Maybe the install was problematic, I don't know. This error only shows up if there are different file sets.
