I only played 2 or 3 hours after installed the latest download. After about an hour I looked for friends and nothing showed. Before the patch, friends showed even if they were not logged on or playing another game. Now there is nothing. I heard that sometimes it take hours to populate your friends. One of my friends could see me and others last night. Some of these places need you to have your friends with you.
