Minor update to fix some matchmaking issues. One was where if you were invited and then joined the queue from the bottom menu, you didn't go in the general queue.

We also reworked some logic around changing modes and player sizes. Sometimes bad things might happen if players joined and left. We've put some more guardrails to prevent bad combinations and try to make better choices if someone drops while in queue.

Hopefully that settles down the main matchmaking queue bugs--we'll be focusing on making Custom Games more flexible, getting all the options working, and after some testing we'll put them front and center instead of hiding them in the corner.
