I think, RHS vs. BAF compat. addon broke the mission. They are dependent on other addons. Problem occur, when you want to load a save, and game tells you it's missing some PBO.
Yesterday I completed the game without RHS-BAF compats and it ran just fine.

@Hanz(z) Addon 'UK3CB_BAF_Units_RHS' requires addon 'UK3CB_BAF_Vehicles_Chinook' this?

Yes, then dependecies accumulate. I add like 4 additional mod dependencies.. I end up with ACE, because I know ACE medical system is not compatible with Ravage.
I have no problem with this modlist:

CBA
RKLS Studios Attachments
RHS all
BAF Equipment
BAF Weapons
BAF Units
3CB Factions
@Horror mod
CUP Terrains Core
CUP Terrains Maps
Diwako's anomalies
Namalsk R
Ravage
JCA M50 APR
Simplex support services
Military Gear Pack

+ some minor mods like Enhanced movement, mag repack...
I encourage using m3mory mod, which helps with saving performance in long lasting SP mission.

@Hans(z) Ok i am going to remove the BAF Compat mods, i have just tested it and it worked alright
