[Bug] Leaving a game after the citadel is destroyed breaks other players' UI.

Just in a game where someone disconnected right after the citadel was destroyed before the score screen.  This caused the eject UI to appear underneath the score screen and not go away which led to me having to exit the game via the X (windowed mode) since the rest of the UI was blocked by the eject screen (even though it was in the background).  Ejecting players and waiting did not resolve the issue.
