‘CRITICAL ERROR: Important SS2 data was corrupted in your save’

I’m met with this warning after loading my save after installing chapter 2. I have none of the listed mod conflicts, I updated all of the necessary mods, the recommended load order is correct etc. what could be causing this and is it even safe or worth it to keep playing? Does this mean the mod is now completely busted on this save? The message itself gives pretty mixed signals and I can’t find any information anywhere else about this specific error message.

Thanks in advance.

Does the message say "As much as possible was rebuilt-"? If so, my saves work perfectly fine. I would personally not install mods mid-playthrough. :)

Thank you for the response! Yeah, It did finish the warning off with “As much as possible”. I’ve played a few hours since the warning and it seems totally fine. My bad though, I assumed it would be okay to install mid playthrough as I viewed it as like an ‘episodic DLC’. I finally got round to continuing my old playthrough when I was reminded the next two chapters were out!

The cause of this message is often, Fallout 4 unloaded from memory, some settlement related data, Sim Settlements 2 needs to function correctly (it does this in vanilla too - one example is when your pipboy shows wrong values). Luckily it can generally be rebuilt - and Sim Settlements 2 can now recover from such a situation, instead on continuing with garbage data.

Nothing wrong with adding mods mid-playthrough. You just can't remove them.

I should of made it clear that adding mods is not the cause of this, my bad.

I would always make a save and test the added mod though. :)
 
Hey I keep having this error show up. I have Buffout 4, Sim Settlements 2 ch 1-3, ufo4p, and the only other script heavy mod I have is Gun for Hire and a few weapon mods. I only install mods at the beginning of my play through but I run into this error without fail every time I load a save after doing anything Gun for Hire related, what could the reason be for this? Last time I continued on after receiving this message my save files became unrecognized by the game after a while (though I’m not sure that is a related issue) Is that something that others are experiencing?
 
I'm experiencing this too. Even got back to my old save several hours before the first time it happened, but after some quests and exploring I ran into it again.
Sim Settlements seem to function normally. I only have a few settlements and they're all fine. I tried recalculating and resetting everything that can be recalculated and reset - no effect. It's the same error at the loading the game. It doesn't appear if I'll load the same save after the game is already loaded. Can it be a false report or something wrong with the latest versions of the mod? I've only encountered it in 3.2.1 and it's still present after updating to 3.2.2.
 
What I do is make a save with nothing going on. Load into it. Give it a few minutes. Load your last save. I dont normally get an error side loading in that way.

According to Kinggath the message is caused by one of the invisible items SS2 uses to record your data in the mod was found corrupted, missing, or not there. The game will put it back but a bit of data might be lost.
 
It's a bit confusing, as I am now running into this error a lot, and it's a... mixed… message?
Like, is it actually a critical error or is it not? What can I do? I tried reverting to the save before the message first appeared - twice. No dice.
Is it ignorable? Because I sometimes see several of them in a row after loading the game.
I found some missing resources in Sanctuary - it recovered itself, but now I don't know, if it's related to the messages and if it's really safe to continue the playthrough as these errors keep appearing. And I never had these problems with SS2 before.
 
According to Kinggath that message is generated when some of the invisible objects SS2 uses to record information on are missing / corrupted. SS2 will try and replace them but the data they held will be lost. Basically things arent terribly broken yet but its a heads up that something may be going wrong. In one game I got that message plots in town would upgrade to completely random plots :P

Are you using a mod that lets you delete more things? I have a theory that one of them will allow automated system to delete things it shouldnt be.

If you can Id hop back a bit to an earlier save. Also the message doesnt seem to trigger / have a problem if you load your old in Vault 111 save and then load your current game.
 
Yeah, I'm using Scrap Everything with Scrap (Not Quite) Everything and previsible patches. Mostly to remove some small junk.
Never was a problem before though. No auto-scrappers, "clean settlements" or such.
 
Ah ok Raze my Settlement wipes the settlement clean - Ill have to go back to the drawing board on my idea.

Oh you might like the mod 'Insignificant Object Remover' :)

Scrap everything is a known issue with SS2. Per the wiki:

Scrapping Mods like Spring Cleaning or Scrap Everything​

  • These mods may break game precombines, causing performance issues.
 
That's why I'm using precombine repair right over it. Don't have any problems with FPS aside from the usual Fallout stattering here and there.
My theory is that SS2 is trying to access some information before it's even loaded, fails and thinks that something is corrupted.
Loading into a save in some small cell allows the game to load fast enough for necessary data to initialize before SS2 checks if it's there.
Otherwise, is the data was actually corrupted, it wouldn't matter which save to load first - loading of the corrupted save would trigger the message every time.
 
I do, hovewer, see some instancing of SS2 having trouble to access their data - even in saves without any warnings.
Here is me arriving to some recently established settlement. As you can see, the resource panel at the right fails to get any actual info on the settlement. Recalculating costs and production does the trick and I'm seeing actual numbers instead. Buuuut… sometimes the resources appear in red (even if I'm just standing there doing nothing. It fixed itself over time, but all in all, in combination with a "Critical Error" above… I'm really worried.
 
Have you had any plots come up as empty when they should be full/building a new building you didnt tell it to?
 
Nope. There are only a couple active plots in this particular settlement, so it's easy to spot.
First time I had this problem, in Sanctuary, I've manually refreshed each and every plot just to be sure and didn't found any problems.

I had this issue, it was from a corrupted update from windows 11 did a fresh reinstall of windows 11 and works Perfect with no issue.
Does Windows 11 work well with FO4? I havent found a solid answer (also the spyware looks intense).
