We've been trying to play COD BO2 Zombies with around 5-8 friends at a time. We know about the Privacy Party settings and setting the Max Party Number to 8, and we know about the command "xpartygo" to force a game start. The issue occurs when we try to connect together in a party, usually only 5 of us can connect to the Pre-Game Lobby party, and if a 6th does successfully connect, one of the players would be kicked out making the amount of people in the party 5. When we do start the game, a 6-7th player can connect, but the 7-8th would constantly disconnect, resulting in them having a black screen, or complete game shutdown.
This issue also happens in Multiplayer. Even with the party players set to 18 (Max), after the 5th player connects, everyone else afterwards has a hard time connecting or don't even connect at all.
If worst comes to worst, we'll probably just set up a server, but because that takes alot of effort, does anyone kknow any possible fixes or solutions that may help with the connectivity issues?
