Flagged

Once you are flagged off the standered room server, is it forever or for a limited time?

I have not understood the problem ... you can develop ?
You speak of rooms multiplayer "Casual" , "Standard " etc.?
All I can tell you is that the Matche mode usually lasts 5 minutes (but the admin can change it) , and the CTF ends when one team has 5 flags. Similarly, this number may vary according to the admin.... but I do not know if you talk about this.
