Very strange NPC glitch in Riverwood

[Aki K]

There is a spot in riverwood where NPCs get stuck inside one another and they just stay there FOREVER.  I mean literally nothing can get them away from that spot once they're in there.  I tried killing them (dead ones sink into the ground but one of them can't be hit no matter how close I am to them).  I tried disabling one of them.  I tried Unrelenting force.  I tried "moveto player" command.  And if I use the "wait" option more get stuck in there once the time passes.

 

If I use "mark for delete" on all of them, the space is unoccupied, but eventually another NPC gets stuck there if I wait even one hour.  It'l like it's just sucking up all the NPCs in riverwood.

 

The only mods I have that effect riverwood are SOS (which adds a shop some distance away from the glitch area) and deviously cursed loot (which adds one NPC inside the inn, so not even the same cell).  This doesn't make sense to me.

 

Looking for someone who knows what the hell can cause this and what the fix is?  It is always the exact same spot where NPCs get stuck.  Started with 2 whiterun guards but then Alvor and some other NPC got in there.

 

 

 

EDIT: Other NPC is Sigrid.

 

I tried loading a previous file.  The spot was unoccupied and I tried waiting (it was night and I couldn't see too well).  For a while it seemed to work fine.  killed a thief trying to break into the trader.  Once I turned to look back at the spot it was still unoccupied until suddenly, Sigrid just spawned into it and got stuck.  i deleted her, waited, and Alvor got stuck.  Deleted him, waited, and then the spot was seemingly free of the glitch (No one else was getting stuck there)  Though in theory white run guards could get stuck there since they were the first victims of it.

 

Am I to go the rest of Skyrim without these 2 NPCs?  Why is this even happening?

Probably, you have a bad NavMesh. Disable mods until found the problematic mod.

Will try that.  What is a navmesh?  I've heard the word but don't know what it is.

Road mod?

No road mods.  That area should be totally uneffected but something is causing trouble in that exact spot.  Sigrid and Alvor seem to be at the center of it, because if I delete them the glitch stops completely.  But I don't have any mods that alter them except the CBBE body and SOS body, as well as skin texture mods.  I'm inclined to think if those mods were the cause this problem would be effecting a lot more NPCs.  But only that one spot and only if those two NPCs exist.  For now I've just deleted them from that save and called it a day, but I would like to understand the problem better so I can fix it.

 

GenioMaestro said it's probably the navmesh.  In my experience he usually knows what he's talking about.  Sadly though, I don't always understand.  My technical skills are low.

Simply put, a navmesh is a collection of polygons that tells an actor where it can walk.

https://www.creationkit.com/index.php?title=Category:Navmesh

Navmeshes represent the actual area that Actors can walk on. A Navmesh consists of a list of triangles (composed of verts and edges), derived data such as slope, and additional information like cover, preferred paths, and water areas. Navmeshes allows the AI to build better and more efficient paths based on data added to the Navmesh in the Editor or generated dynamically at runtime.

 

Alvor can walk from the forge to their house because the game have a group of NavMesh that define where are the stairs of the forge and where is the road.

When the NavMesh not exist or is bad defined the NPC's can not know how go from one point to the other and normally they walk over the same point whitout move.

When you make a teleport to the cell and the cell not have NavMesh, the game position ALL the actors in the center of the cel, normally one over the other, causing the fail that you show in your screenshot.

The NavMesh are written inside the ESP's and, probably, one of yours ESP's have a bad NavMesh for RiverWood. The most easy way to locate the problematic mod is disable mod until you locate them.

 

The other way is open your entire pluging list in Tes5Edit, get the code of each cell from https://www.skyrimsearch.com/categories/cells/1/Riverwood/ and open every one of the cells to see what is the last mod that modify the NavMesh in that cells.

Would you say the last method is more efficient to finding it?  It sounds easier.

Normally, for a normal user whit low knowledge, is more easy disable mods. But if you know how manage Tes5Edit can be more easy to you use Tes5Edit.

Have in mind that Riverwood have 10 exterior cells and each cell have from 2 to 5 NavMesh inside the temporal definition, that give from 50 to 500 diferent NavMesh and you can need some minutes to revise all of them because the fail can be in any of the NavMesh.

True, but if I know which cell I'm dealing with it shouldn't be so bad.  I've never done anything with cells in TesEdit but I have learned quite a bit about TesEdit so it might be the easier route for me.  I just need to figure out which mods are effecting that cell recently correct?

[Aki K]

I tried looking up riverwood cells.  I found the ID for all of them but it doesn't seem to tell me which one is for where.  I guess I'll have to go through all the exterior cells until I see deleted navmeshes?

 

EDIT: Okay i did a line by line search of all the navmeshes for the Riverwood cells and as far as I can tell nothing was deleted.  Certainly nothing was marked deleted.  Most lines were highlighted green, some yellow, a few red.  Not sure what that means but they all had values written in the lines usually.

 

It seems the only mod that's modifying riverwood is SOS (which adds a shop) but SOS has been installed LONG before this glitch started occurring.  So I'm at a loss as for the cause.  But at the same time I don't really understand what I'm reading or how to look for it.  So maybe I already mentioned something that's a red flag.

 

Alternatively, I noticed not every cell I searched in TesEdit lists navmeshes.  Some just have "placed objects" but this is also true for cells that are fully functional like ones form solitude (no glitches there but I'm seeing a lot of the same stuff.  Reds, greens, yellows.  And sometimes just "placed objects" in some cells rather than navmeshes.

 

So in short, I don't really know what I'm looking at and therefore can't tell what is out of the ordinary.  I see tons of values, but I don't know if red means deleted or just overwritten by something else.

 

 

One thing I find odd is that there should be at least one other mod adding something to the cells in riverwood.  One of my mods adds an NPC to the interior cell of the inn, but that wasn't listed when I searched that cell for comparison.  It would be easier if I knew exactly which exterior cell in riverwood i needed to search, but all of my googling gets me the form ids but no descriptors.  So i had to search all of them and maybe I missed something.

 

EDIT 2:  There's also the fact that it only occurs with two very specific NPCs.  if I delete them it works fine.  If they're around they always get stuck and drag other NPCs with them.  But once they're gone, no issue.  So maybe it's related more directly to Alvor and Sigrid?

Hi so something interesting happened.

 

I started a new file and the glitch was gone without anything changing (I never found a deleted navmesh).  But about halfway through the playthrough the glitch happened again, but in dawnstar and with different NPCs.  That doesn't sound like a deleted NavMesh if it's in a different location for a different file.

 

 

Edit: I should also mention I have no mods that significantly alter Dawnstar.  The only city I've altered to any significant degree is Whiterun.  The only mod I have that effects dawnstar is Deviously Cursed Loot which adds a single house at the very end just before the dark brotherhood lair.

[Zebot]

Try to disable Deviously Cursed Loot, make a new save, clean the scripts from the save with a cleaner and try it.

 

For what i have researched, that might be the culprit of the Npcs ( at 1st glance ofc since we dont have your mod loadout to see in more detail)

Could swear I put the load order but just in case I will put it below.

 

I never had this issue with DCL before.  That's strange, but I'll try it.  What has your research said specifically?  I'm curious if there is a fix because I really like DCL.

[Sgt. Marge]

I think I was having the exact same navmesh problem as described here, NPC's were having a traffic jam on the road right in front of the forge in Riverwood near Alvor's house.  It looks like the same spot as the pictures posted by OP.  I was able to resolve it by disabling the SOS - Shop.esp file.  No more traffic jam!  I never used the shop but I'll miss the shirtless man that ran it...

 

I know this is a year old thread but I just wanted to post this in case someone in the future finds this thread and maybe it will help.
