when you accept an invite to a party while joining a match the friends tab stays open

[tall mantle]

and you cant click on any other tabs until you restart the game (you cant access the main menu). if u join a game cos ur leader searched and got in one the tab goes away until you get back to the main menu

its quite easy to replicate ive done it maybe 5 times by accident
