[CLIENT] Receiving a "ghost invite" while playing Blood Moon.

I was playing Blood Moon with friends, but each time one of my friends invites me to a game, I get two invites: One from my friend, and another from a friend I was playing with previously but went offline. Clicking on the "ghost" invite comes up with "this game does not exist".

Unfortunately I am unsure as to how to reproduce this bug, but it occurs when one player in the lobby has Low Priority (In this example, it was not the person who was sending me the "ghost invite")

I am also on a Macbook, so that may also contribute to the bug.

I have had 5 games with my friends thus far, and so far it has occurred 100% of the time. I am yet to test whether this bug occurs when queueing for other gamemodes besides Blood Moon.

As you can see, the invite from "SAMdaWISE" is the "ghost invite", as he was offline at the time, and was for a while after the bug started happening.
