I hope it's ok I chime in here, instead of opening a separate topic, since I believe my issue is related:
My game crashes trying to approach Revere Satellite Array with SS 3-in-1 and Conqueror 4.0.8 installed. I have a save file just steps before the crash reliably occurs.
Switching to 4.0.7a and 4.0.7b in my load order and loading up the same save file, I can successfully enter and clear Revere Satellite Array. Nothing else changed in the process: Same load order, same set of additional mods, same set of addon packs, and so on.
There are (to my knowledge) two settlements in the vicinity which might play a role, Finch Farm and County Crossing. Both I haven't touched or entered or even scouted out/discovered yet, so they should be pre-built to level 1.
My (uneducated) guess therefore is: There is something going on with 4.0.8 in the background which overwhelms my system, but my system can handle with 4.0.7, even though I'm not in a settlement at this point, just in the larger vicinity.
Some additional info that might or might not help:
I am one of the unfortunate people cursed with a rather unstable system when it comes to city plans, so I have developed a personal set of 'best practices' which work for me, like starting a new game with just a minimal set of mods, being really careful adding mods, regularly checking my saves in Fallrim Tools, rolling back whenever there are unattached script instances, sitting in interior cells to let scripts cool down, and so on. I only ever build one city plan in the Sanctuary-Red Rocket-Abernathy Triangle and leave the two others empty, avoid building too many plots in Starlight, stuff like that.
(Probably unrelated,) this particular playthrough is supposed to be a Children of Atom playthrough, so I'm using the CoA Faction Pack, started the game with Start Me Up in Parsons Creamery and went straight to Far Harbor (Conqueror not enabled at the start, I enabled it only later, before I unlocked the first workshop, sitting in an interior cell and waiting through the entire Conqueror pre-build process which takes about 3 hours in my system), stayed in FH for 30+ levels, I have one manually built Outpost there and three Vassals all with city plans at L3, and strangely enough didn't have a single crash in all this time which is quite unusual on my system. Only now, returning to the Commonwealth, I ran into this strange issue...
Again, I hope this helps somehow, and whatever is going on with 4.0.8 I'm sure you guys will figure it out eventually. And I will keep on playing whatever content you put out in the future, finding ways around my system's limitations where necessary, because I love this sh*t so much-
Keep the good stuff coming!
