We are looking into the issue of updated servers NOT showing up in the browser. For now, connect via IP. Look in the forums for some.
We also strongly suggest those who are crashing on the new build to try turning down their settings. You may be running out of memorry on one of the new maps.
We'll be working hard tomorrow while some of you are enjoying your holiday to try and figure these things out!
As always, we strongly recommend you check out hte performance settings listed Here while we search for why some users are having subpar performance . Keep in mind, the larger player count servers will require stronger hardware to maintain performance. More is going on and more has to be rendered.
