Coop Overlord Map not expanding to phase 2

Playing online modded Coop Campaign with a friend on Operation Overlord. We complete phase 1 of killing the first base then the game does the voices for fletcher going crazy but the map does not expand nor play the cinematic. We have not had this issue with any other maps. There have been some issues with one mod not allowing the game to load-in but we switched it off.

Adv target priorities
No Shake
Supreme Score Board
All faction quantum gate
auto reclaim (dwm)
oof ACU death sound
ultra shields

Mod causing load-in problems:
Total Mayhem
