Why my custom mission always lose connection when i want to play with friends


As long as player hit another player, all players can no longer connect to the services. Is that a bug?

I’m probably wrong but I’m going to assume that its bc you are the one they have to keep a stable connection with.

Do we know if custom games rely on any form of hybrid networking models?
