ClientError: Only the party owner may enter the party into a queue.

Tracking issue.

Describe the bug
I'm seeing this error message showing up in the log files. It means that somehow the client is sending a game_matchmaking start command while the player is in a party of which they are not the owner. This could be due to a client bug, or a server bug or combination of both.

I recall a server issue a while ago where it would sometimes think you were not the owner of your own party but I am unable to find a link to it at the moment.
