Hi. Since you said you haven't seen problems with Total Mayhem or Orbital Wars, I suspect the desync is caused by a combination of our other favorite mods and those two big mods. However the smaller mods worked fine for us as long as we don't use Total Mayhem or Orbital Wars.
Nuclear Repulsor Shields
AI-Uveso
No Air Crash Damage
Jaggeds Infrastructure Pack V2
NoShake

I will try to experiment with combinations of the mods when we play next. Probably tomorrow.
