hi, i have a co-op L4D2 server and when i added it to my favorites in the server browser, it sometimes disappears for about 5-10 seconds and have to keep refresh and then it will appear again for only 5-10 seconds agin, I have noticed that other servers always stay on there sometimes only disappearing for 1 second or less, is there any way that I can keep the server showing on the browser. thank you
