Wow that settles it for me too. I want to get rid of Scrap Everything I was wanting to anyways because of it disabling pre combined.
Can I just disable it or do I have to start a new game? Kind of got some decent sim settlements I'm liking so far and like noted in other topic Transfer Settlements doesn't seem to handle SS plots very well.
**1- YMMV but general rule of thumb with skyrim/FO4 is you'll never have as stable a game if you remove mods mid-save than if you start scratch. That said (notable exception being non-esp/esm pure texture mods which is removable/addable willy nilly.
My exp has been if you didn't go too crazy with SE, then you can reasonably remove it mid-save. But all the objects you removed with SE will come back fyi.
**2- Re: Place Everywhere extra object selection (= key) :
By default off, when you go into workshop scrap mode, you're basically using vanilla scrap ability. It only outlines and grabs items totally safe to delete. Using = key to turn on extra object selection allows you to grab additional also-safe to delete items not normally grabbed by vanilla system because it is linked to pre-combined objects.
Scrap Everything unlinks every single object into an individual one, which is how it is able to grab and delete almost anything. But this means if A-B-C items are all part of pre-combined objects, the game expects A-B-C to all exist, or to all not exist.
It can cause AI insanity if only A-B exists because you used SE to individually remove C, when it is really pre-combined with A-B-C. What PE does with extra object selection is when you mouse over A or B or C, you are grabbing all 3 and deleting all 3. This isn't to say from time to time you won't mess up with PE, so always safe to save before you start to delete anything, but for most part, practically anything PE tags as outlined via extra object selection mode is safe to delete.
You may get some ugly looking blanks or voids in places because the game never expected A-B-C to be gone, but it wont go AI crazy like if A-B existed when it expected all of A-B-C or none of A-B-C
**3-Re: Clean and Simple load order
a) if used solo, doesn't matter where
b) if used CAS + PE, doesn't matter
c) if used CAS + PE + Settlements Extended -- it depends if you used the (1) settlement Jencave not only cleaned but modified different look, borders, etc
c1- if you used one or more individual settlement downloads, they all need to be above Settlements Extended, and PE can be anywhere (best wherever Loot puts it)
c-2- if you used her all-in-one single esp that combines every settlement she's done, which is all vanilla except Hangman's Alley in that pack, then that one esp should be above Settlements Extended, and PE anywhere
c-3- if you used her Hangman's Alley separate mod, with or without her all-in-one combo esp, then it needs to be like this:
--blah blah your other mods
--Clean and Simple combo esp
--Settlements Extended
--Hangman's Alley
***AND --> you need to use the version of Settlements Extended that does NOT include Hangman's Alley.
****I would recommend using the safest performance option especially with Sim Settlements -- the version of Settlements Extended that does NOT include Bunker Hill or Hangman's Alley. The BH modification can screw up vanilla quests with Liberty Prime and make performance a big negative. No quests I know borked with HA but same congested performance hit (usual caveat that if you have an insane enough gaming rig, there is no such thing as performance hit, but reasonably speaking - you're better off with both BH and HA excluded from Settlements Extended)
The TLDR is I use PE (Place Everywhere), Jencave's CAS combo + individual Hangman's Alley makeover, Settlements Extended option excluding BH (Bunker Hill) + HA (Hangman's Alley), and of course Sim Settlements with about half the available add-on packs, plus Transfer Settlements which as noted is kinda iffy.
d) Last note re: Transfer Settlements in this giant wall of text - after a lot of trial and error last week with lots of save restarts and imports, you can reduce some of the hit/miss of importing SS objects by doing two not-so-guaranteed-but-better than normal borkage ---->
d-1- when you EXPORT the settlement in the first place, do not use the export non-player made objects selection (first option check). Even though you'd think can simply choose to not import whatever chunk you don't want (Non player made, player made vanilla, player made DLC/Mod, and player made SS special selection), I've found that the mere presence of that extra data in the exported file makes imports with it kinda wonky (*totally technical term)
It is also purely my exp and could be total superstition but I've found the least data I export the better, so I also don't export connected power lines.
I just export selection 2 and 3 (player made vanilla + DLC/mod objects) and the safest SS version is export only the SS plots (not the buildings or their upgrades. The most time is terraforming your ground to lay down the plots, not click the ASAMs and pick a building so I like this option best.
And may totally be only my luck but so far I get the best accuracy milage by exporting only that data, and importing only that data.
***And if you read the entirety of the many pages of posts on TS forums, you'll fine that regardless of Sim Settlements objects or not, TS is really wonky about importing. There are literally guides that tell you from respectable authors and mod authors to put yourself in view Pipboy mode when importing to avoid CTDs and unstable imports (e.g items missing, objects floating around, etc)
I believe them, but my common sense rule of thumb is if you need to stare at the blank ground or at pipboy screen to avoid over-taxing the import ecosystem, that mod is pretty much one foot on a banana peel and one foot in the grave already. Doesn't mean I still don't like it and use it, but as noted, it is pretty wonky just by itself regardless what mod data it is trying to save/export.
