Experiencing some strange issues here in both of these missions. Playing them single-player they work just fine (with some minor expected glitches/bugs) but when I host the campaign in multiplayer for me and my friend we are unable to trigger the endings. Or rather, the missions abruptly end at around the expected point (or so I think) in the mission and unceremoniously dumps us back at the mission selection screen, but the next mission has not been unlocked. "Resuming" the mission just loads the mission and then dumps us back at the selection screen a split second later without a chance to do anything.
The first two worked fine, but to get to mission 4 I had to play mission 3 in singleplayer first to unlock 4, and then host from the start of 4. Surely this is not intended.
