Cuz u are one of many that got a error today. Its already made threads about it. http://shellshockliveforums.com/index.php?threads/friends-list-going-crazy.5189/
I'm assuming from the above posts that "can" actually means "can not" as my friend list has been removed as well. These are things potentially being worked on as stated by Kyle Champ here: http://www.shellshockliveforums.com/index.php?threads/server-errors.5186/
