EA/DICE once again has borked an update... Servers not showing up, friends list you have to re-accept invites.. The only server showing up in the browser was the Hardcore Moxed... I reset the GUID on the HC Air Maps and Conquest 2x Tics servers and they now show up in the browser...
If you are still having issues seeing the servers in browser, use the "Com's" in battle-log and find a friend in the friends list that has saved the server in their favorites and the option to save it as your favorite will be there.
