Desync only on 1st Coop mission

[RK4000]

Got a desync, first about 55 beats into the game (if my memory serves correct) on the first Coop mission.

Additional info is that my friend didn't see the cutscene playing, and i did. After the initial desync it didn't go away even after the cutscene ended, so we just stopped after a minute or so.

Also, mission 2 and 3 worked just fine and we've played through them no problem, so it's just the 1st mission being problematic.

You probably don't have the correct map. Erase your map, tell your friend to erase it.
