Yeah it looks like one of those mod updates wiped out the relationships between game forces.
Not sure which one it was, and a few of your mods don't seem to be on the official portal so I didn't spend a lot of time investigating.
I added some code to rebuild the relationships whenever there's mod configuration changes, that should take care of that.
(Nothing I can do about whatever wiped out the exploration on your map, nothing my mod does should touch that)
Thanks for the save, it made it way easier to figure out what was going on.
Your save now works fine on my machine, if it still doesn't work for you let me know.
If necessary, possibly I could send your save back to you?
I'd need the mods that the portal didn't have:
MoreAchievements
Shield-FX
Soundpack-alerts-and-sirens
belt-reverser
ctg
speaker-signals-expansion
I have released version 1.2.11 with what should be a fix.
The new version should start to appear in the mod portal shortly.
