I see all of these updates by 343 talking about Matchmaking, Matchmaking and Matchmaking but nothing about fixing co op. Every time a friend and I try and start a specific mission from the campaign menu it crashes with a “lost connection to host error” and sometimes that is followed up by a “Party is full error” which is ridiculous since i am the host and the campaigns allow two players. The only way my friend and i can play is to do the playlists which dont help when you need specific skulls to get to terminals, easter eggs and other skulls.
