They have a known issue atm, its mainly related to team balance. If too many people land on one team, it makes the server laggy, but the system itself seem to be okay right now

Hello, this notice is going out to all of our Bad Company 2 customers at Art of War Central.

We are currently readying for deployment the new Battlefield Bad Company 2 R9 patch. That patch introduces several new features and bug fixes:

• admin.say command implemented
- the output currently looks a bit funky on the game client, like so: Player: [Server]:
but with the next game client it will look like: Server:
• admin.yell to squad has changed (you need to specify both team and squad)
• squad numbering has changed – the “no squad” squad has ID 0, and real squads are 1 and up.
• Autobalance improved, it shuffles people both during and between rounds now, and does a better job
- Currently there is no way to turn it off
• mapList* commands reworked
• banList* commands reworked
• listPlayers command added
• admin.listPlayers command reworked (GUID, kills, deaths, ping and score added)
• Players have non-PB GUIDs now (these are distinct from PB GUIDs)
• onChat event reworked
- now it specifies target player subset as well
- shows text before profanity filtering
- client-originated chat messages starting with “/” make it to the server, and broadcast via onChat, but are not broadcast to other game clients
- use “/!” if you want to be able to send commands to your homemade rcon tools without showing the commands to other players
• player.onAuthenticated added (it’s triggered when a player receives GUID)
• player.onSquadChange, player.onTeamChange implemented
• Couple of crash fixes
• Support for server-side “region” setting (not yet used by the game client)
• Ranked ON forces game-password OFF
• Ranked and PunkBuster settings can only be changed during server startup
• A server is marked as "hardcore" either when Hardcore is enabled, or when all the typical hardcore settings (hardcore killcam minimap etc) have been flipped
• exposed number of rounds per maps in maplist.txt, and via the remote admin commands

Note also that we will be enabling an option to enable debugging logs if your server crashes alot. That'll help us debug your server if it crashes.

The R9 patch should be available this afternoon.

Thanks
