Hi,
Most of the Australian lobbies run off servers booked from ozfortress. Ozfortress automatically unbook the servers after 15 minutes with no one online, which is a problem for lobbies if they take more than 15 minutes to start, it makes the server unbook and the lobby dies because the server becomes unavailable.
A simple solution to this problem is to force the host to join the server when they create the lobby, so they are on the server while the lobby is filling (perhaps detect whether its an ozfortress server before forcing them?), and remove auto-kick from the server (probably using rcon) to make sure they don't get kicked from the server while the lobby is filling.
I hope you consider this suggestion, it would fix quite a few Aus lobbies dying because the server becomes unavailable.
