I am an ADMIN on several custom servers, so I know they are up, but I cannot see them. Even when added to favorites. I have to refresh over and over and over, etc..., to get them to show. I spent 15 mins yesterday refreshing to finally pull up a newly added server, that friends were already playing on. When I refresh the server list I get huge ranges in the amount of servers I find, 30-120. Even with 120 found, I have never seen all 6 servers I have on favorites. For those that don't have the IP's this can be a terrible experience. I have friends that never have this issue, where I have it every time.
