Strange behaviour after canceling a que (CLIENT)

This has happened a few times to me now, and the only way to stop it seems to be running a repair. After playing a game with people, either by requeing with those people or simply leaving the que after it has started the client appears to freeze although most is still working. All conversations no longer scroll after text has been sent to or from people, and if a message is sent it then repeats sending everytime a new message is sent. Also no text appears in the chat in any group lobby before the que or match starts, with the in que party conversation not being present. Furthermore, the accept and decline feature no longer shows any boxes of other plays accepting or declining the game, only one box which looks similar to the view profile page box next players in a lobby.

Curious if anyone else has experienced this since it has happened a few times now, and i know my friends have experienced weird communication disruptions and had to relog as well. Hope this brings light on if this is an issue with others
