lost object references tends to happen now and then especially in heavily modified game, so I suspect this is not an issue (unless it happens many many times)

Did you try playing the game in
developer mode? And set the debug log to pause on error. This allows you to see the error when it happen without having to look into long log files. Also allows you to see how many times the same error

reference exception causing it, but it is related to a Haul Urgently command for sure. Could be from issuing a "Haul Everything" command or accidentally selecting a Fogged object to haul.

I dont see anything
.

Backstory related or not, I think that is definitely why none of the raiders spawned. There was an error with their min and max age that was causing them to not spawn.

Error while instantiating a mod of type

mod that will be listed on the workshop page so should be easy enough to fix.

There are other instances of errors related to missing a required mod that doesn't related to objects, perhaps it's a
Cross reference error means one mod is looking for objects from another mod and not finding them.

Could not resolve any root named X means you are missing a dependent mod that defines a base item

I'm not a tech guy at all. The game wont even let me deactivate any mods that might be causing an issue. It comes up with these error messages, which means absolutely nothing to me:

Its like there is files left over the Mechadroids mod being enabled, also I think the "List`1" is referring to a mod called Stackable Chunks

The saved data might reference something that was half-calculated or no longer exists, leading to:

Crashes on load.

"NullReferenceException" errors as the game tries to access missing objects.

Weird
dozens or even hundreds of hours. The game's longevity and replayability are its greatest strengths. A architecture that allows save corruption is an existential threat to this model. Players would be far

to not break the laws of physics.

Even if a pilgrim would think a minigun is a device of witchcraft, it would still be possible to explain what a minigun is and how it works.
