I got into patrols, and there were SUPPOSEDLY 8 people, 4 of which were not in yet, and I figured they were just taking a while to load in (I join late all the time). BUT THEN, about halfway through the battle, they STILL weren’t in, and their names mysteriously vanished from the list of allies in the top corner. needless to say we lost, and the MM is doodoo. 
That happened to me this evening too. Was doing a wires battle, 8 vs 8, and only 5 people on each team were loaded in when the thing started. Halfway through, the unloaded-in people’s names on both teams all disappeared.
After that, I was checking out one of my cars, made a change, then decided to scrap the change. The screen wouldn’t let me revert, save, or leave. I had to restart the game.
Then, I was playing the drone apocalypse thing, got nasty lag, and finally got disconnected. I had to restart the game again. Wierd night…
