The official servers have a couple of pretty game-breaking problems currently inflicting them. The command to vote admin, both via typing in the chat and going onto the map to do it via the player list is currently impossible, meaning that the servers are stuck with the default mission settings and difficulties, making it nearly impossible to have an enjoyable experience without basic concepts like reviving, which is also disabled by default.
Going hand in hand with the inability to vote a player as an admin, the vote kick command seems to be non-functioning at the moment.
Furthermore, the global chat seems to be disabled in some form or another. Given that Zeus is a virtual entity in this mission, this means it is impossible for the players to properly communicate with the Zeus. I've seen instances where the Zeus communicates with hints, but that is about the extent of what can occur. Furthermore, names do not appear in the bottom left corner as they should, meaning players cannot see who is speaking. While this seems trivial at first, it creates major issues when you have players begin to blast music over the microphone at a deafening volume; only cementing the need for a player-voted admin.
