All you people who could not select sides could you recreate this bug please by going into a populated server and try click the flags before they appear and before the map has loaded. In my experience you get the same effect. If you wait for everything in the menu to load fully before clicking anything it will be fine 9/10...
I think the slow loading of menus may have been caused by our admin. The remote access was using 33% of the traffic to the server. Obviously in the future he will only set in running and then leave it for the course of the mission so it should not be a problem in future.
