Question SS Breaking Interior Cell Pathfinding

Lengthy post, but wanted to share all the info I have.

I have an issue in which if I have SS active with particular other esps, then AI interior pathfinding breaks in multiple different cells. This results in both Allies & Enemies standing still and idling. If they have guns then they will shoot and they will dodge gunfire, but they will not move forward. If they have melee weapons, I can stand right in front of them and they will not move nor attack.

I have had this same issue twice. The first time, I had removed mods mid-game (I know, frowned upon) and Fallrim showed that I had a very borked save file, so I started over. My current save file has not had a mod removed & yet I run into the same issue.

The first time around, I noticed the issue in Fort Hagen. None of the Synths would come after me, and my companions would not go past the second set of stairs (as in they would not even go the the floor with the synths). If I commanded them to move, they would deny saying that it was unreachable. This issue also happened in the Gwinnett Brewery. I did some testing and discovered that the issue would happen when I had SimSettlements.esm active with either Horizon's Loot Respawn, Horizon Enhanced Settlements, Outcasts & Remnants, Beantown Interiors, or the Caravan Shotgun esps. A few different types of esps yet, when SS was active with any one of those, then all interior AI movement would stop. I checked the NavMesh in CK but (with limited CK skills) did not see an issue. I tried Kinggath's Increase AI count esp but it did not help either.

BTInteriors_Project.esp
OutcastsAndRemnants.esp
Z_Horizon_Loot_Respawn.esp
Z_Architect_EnhancedSettlements.esp
DP_CaravanShotgun.esp

This time around, I noticed something different. In Cambridge Polymer Labs, the Glowing Feral in the radioactive room will not move while in the water he spawns in, but if I use Get Out Of My Way mod to push him out of the water, he'll move and chase me again UNTIL he either get's into the water crater in the main room or if he goes into the small dip in the testing room where the terminal is. The Ghouls upstairs will chase me downstairs but will also stop moving if they get into the crater or the terminal dip. Molly also would not move after I first entered the building, prior to combat starting. I had to leave the building and comeback in for her to start the orientation but after that she would not lead the tour, so I had to "take care" of her to move forward.

My presumption is something in SS is clashing with something else to cause the AI's to lose their pathing between certain levels/floors levels. I've read that edits to settlement workbenches could cause unknown errors, so that could explain Horizon's Enhanced Settlements, why would Beantown Interiors, or even worse the DP Caravan Shotgun cause issues?

If I reboot he game and load in, I'll have about 5-7 seconds of movement before everyone freezes. Reloading would not fix it, just a reboot and then it would still only be about 5-7 seconds. I've used SKK Script Lag Latency Detector and no Script Lags we're noticed. I've tried ReSaver but any save I do will cause CTD on load. I've tried moving mods around in my mod order but to no luck.

I've exhausted all my knowledge, so any and all help would be greatly appreciated!

XDI.dll

I've tried disabling some mods to see if it fixes the problem, only disabling SimSettlements.esm worked.
I've also tried to only leave the vanilla files and SimSettlements.esm, everything else removed and the problem persisted.

Important to point that it didn't happen at the beggining. It started to happen pretty recently in an arround 100 hours savegame. only a few interiors at the start, but increasingly more interiors are loosing pathfinding.

Maybe is a new, previously undetected engine limitation.


EDIT: well i had an idea an went to test it. in this save i had built quite a few city plans, maybe arround 15 of them. I went to every single one of them and scrap the entire settlement. went back to parson asylum (the last place that was giving me trouble) and sudenly pathing was working again. So i think this might have to do with some engine or my own machine limitations. The engine is too overloaded with all the city plans and stops pathfinding in interiors.

The others having this problem, how many city plans have you built?

For anyone still interested in this issue, I have the same interior cell path finding bug that seems connected with Sim Settlements.

The start of the issues have definitely coincided with the number of city plans I have active, perhaps unsurprisingly. No lag or anything, but the interior pathfinding stops completely. I noticed the issue at around 20 city plans

I solved my issue by removing all structures from Vault 88. Apparently, as long as I don't build a Vault, the NPCs will navigate interior cells correctly. At first, I thought the issue was just the Vault 88 city plan because after I removed it (I removed it by removing the city plan, starting the city plan again, and while it tears everything down and starts rebuilding it, I quickly remove it again at the city planner desk. I use console commands to delete any static objects leftover) the problem was fixed. But halfway through manually building the Vault I noticed the problem came back. I quickly deleted everything I built, and the AI started working again. So now I've decided to act as if Vault 88 doesn't exist, which sucks but at least it's better than the alternative of removing Sim Settlements or starting a new game from scratch. I'll let you know if the problem appears again.

Also, I have almost every settlement in the Commonwealth (haven't yet gone to Far Harbor in this playthrough) except for maybe one or two. Removing the city plans from other settlements didn't fix my problem, only removing all structures from Vault 88 did.

I have this issue in Vault 88 as well. The pathfinding for any NPC just explodes after some time. It doesn't matter if we leave the area not not after we start building. The most surprising is that I only used the main sector where the overseer is located.

But this bug only affects Vault 88, it doesn't happen anywhere else for me.
