Server setup bug?

Several times this has happened when setting up a new lobby. I use Windows 7 Chrome. The server runs on Centos6, Sourcemod and tftrue with no other plugins.

When starting a new lobby, the initialising popup goes through but hangs or sometimes gets as far as done. The lobby appears and the server changes map fine. But the sv_password command sometimes doesn't get through. I've just had a whole lobby start using my default password and failing.

To start a lobby now, I'm using HLSW to check that sv_password has been changed. If it hasn't, I have to use the refresh button on the lobby itself. I don't know perhaps if it's sending the sv_password command too soon? Although the refresh button does sv_password first before changing the map. Maybe initial setup does it in a different order.

Anyway something to look into. Great site, and great timing. Poor tf2lobby.
