When joining a lobby with more than 2 persons, connecting clients can join non-lobby-hosting players's parties instead of the lobby, causing them to get stuck finding a match.

I've been trying to fix this by using cheat engine to change the max player number, but apparently max party size is controlled by another address.

I've been at this for like 12 hours. Ill update if it ends up working.

-Ive also had no luck with invites. The overlay never shows up when pressing f5, nor does "auto join invites" work.

So, using cheat engine to force the party slots to be 1 was successful, and prevents people from joining into parties. I can now consistently have 3 people join, but a 4th player seems to have issues connecting. I have had a 4-player lobby work, just its sporadic. I believe there's a certain order that players have to join the lobby in for it to be successful. It's like a particular player just cannot connect. More testing tmrw. It's my friend's birthday tomorrow, and he really wants this to work so, ima try my hardest to be as helpful as possible.

Sorry that I wasn't available to help for your friends birthday. Were you able to pinpoint the problem more?
