Friends List Bugs

When I first long in, my friends list is fine, but after a game my friends list goes out of order and it even puts some friends that are offline ahead of people that are online. Also it shows people are offline when in-fact i know they are online. Also when i add someone after a game and they accept, it doesnt show they are on my friends list. But when i go to invite them to a game, i can. This started happening after the patch.
