[SOLVED] [CTD] Random CTD when carriage/ferry travel

[hotrack]

I play a map-fast-travel-disabled game so generally depend on Carriage and Ferry Travel Overhaul to get to places 'immersively' fast. However, an unusual and persistent problem is a random CTD when trying to use the carriages and ferries. This CTD happen during the loadscreen and don't happen if a fast-travel completes. This has been persistent from my time on 1.5.9.7 and continues with 1.6.1170.

The provided crashlog are pretty much similar with previous crashlogs. Checks in xEdit of the whole modlist show only 2 navmesh deletions, both are the deliberate Cidhna Mine Expanded and JK Winking Skeever Declutter.

 

Notably, sleeping and interior/exterior cell changes do not trigger CTDs.

Another much rarer, random CTD on exterior worldspace normal foot travel (but non-repeatable-non-location-specific) with NO crashlog may be relevant, but with no crashlog generation it's hard to say for sure.

 

 

 

SOLUTION:

Disable vanilla horses RefIDs related to NPCs with DefaultHorsePatrolLinkedRef packages, and change those NPCs packages to DefaultPatrolLinkedRef, and check on mods that have NPCs riding horses on extended routes (Horses on Patrol, Populated Lands Roads Paths), and remove the horse-riding nobles road encounter from the SMQN

Same issue as here I suspect.

 

As you can see in my post here, one of the forum members allowed me to remote control their computer for several hours but we still couldn't work out what the issue was. Since then I have figured out how to get past all the issues, and I now have the ability to use breakpoints in SkyrimSE.exe. Not saying we need to do the same thing on your computer, perhaps just suggesting it's a "Plan Z" if nothing else turns up or nothing else in that thread works.

 

Edit: My point is, this may be one of the more complex issues to have in Skyrim. Generic crash logs ranking "easy" in comparison.

There's a discussion about horses in that thread. When I was on 1.5.9.7, I sometimes saw CTDs when non-fast-travel footslogging in exterior worldspaces with NPC riders with horses, especially when changing cells. Which is why for mods like Populated Roads, I personally xEdited to disable their horses, or when I most notably used Bruma, one horse rider out near that apple farm. I also removed that vanilla WorldEncounter of horse riding nobles from the vanilla road encounter SMQN.

But the vanilla hunter horse riders don't seem to cause CTDs whenever I frequently go through their cells, though they weren't always on their horse most of the time.

However, as my memory serves me right, in those cases references to horses do show up in the crashlogs (which made me think their attempts to pathing was borked). And it was not an always CTD event, just frequent enough to notice it.

 

I'm now going to disable the 3 horses that have associated NPCs with DefaultHorsePatrol packages.

.....

 

I just noticed that Haemar's Shame horse is referenced in my crashlog, and that Nexus mod fast travel crash fix seemed to deal with that. And all discussion are about those 3 horses I guess.

 

The only time I got near Haemar's Shame is when I slogged up to High Hrothgar for Klimmek's fetchquest. But that was ages ago. And these horses and NPCs aren't even persistent.

You may have a point in that its horses (or just mounted horses) causing the issue. But the way I remember it, that crash fix mod didn't fix it for some people. Then again that's not too surprising considering:

1. There's a lot of horses.
2. Literally any mod could add a horse somewhere.

One of the posts did mention wSkeever's contention of horse-riding NPCs trying to go through loaddoors and borking Skyrim for some reason, which I believe I must have read before when I was disabling Populated Roads horse-riders and the vanilla WEncounter horse-riding nobles, way, way back during my time in non-downgraded, non-Best-of-Both-Worlds 1.5.9.7 (which isn't too long ago).

I hope NPC-following horses don't cause a problem as I have the Khajiit Mule Caravan mod added into my merge esp and it'll be a shame to remove it (as well as that horse non-riding peddler world encounter), but then again I've never had CTDs when I encounter/leave them.

After quite some time dreading a CTD whenever I carriage/ferry-travel, I can report that disabling the horses, and changing the DefaultPatrolHorseLinkedRef packages on those NPCs to DefaultPatrolLinkedRef, seems to have stopped ANY CTD whenever I carriage/ferry-travelled.

Weird I didn't notice this problem despite the similar non-fast travel CTDs I encountered with horse-riding NPCs, but that's Skyrim for you.

I got same problem, currently trying to fix it as you told but im a little bit noob on xedit. Is there a quick guide on how to do it? Checking xedit now and cant find anything related to DefaultPatrolHorseLinkedRef etc. I dont know where i should look tho. 

 

Edit, i found DefaultPatrolHorseLinkedRef but at first message where solve is explained, it spelled wrong like DefaultHorsePatrolLinkedRef instead of DefaultPatrolHorseLinkedRef.

 

I still got crash, i did a patch but i dont know if i did it in a correct way. Pic is what i made

so how would I go about disabling vanilla horses refIDs with NPCs and changing the packages? Could you help me through with this? I might have the same or similar CTD issue

You probably wouldn't want to edit 0x68D04, as it would potentially alter other things:

 [00] Skyrim.esm (7CAB85A9) \ Non-Player Character (Actor) \ 00109E3E <SolitudePlayerHorse>

 [00] Skyrim.esm (7CAB85A9) \ Non-Player Character (Actor) \ 00097E1E <MS03Horse> aka. "Frost"

etc.

 

The AI package mentioned in this thread is only referenced in 2 places in my current mod setup (this is with Populated Roads) and seems like the place I'd start:

1. Start xEdit, don't alter the load order.
2.  [00] Skyrim.esm (7CAB85A9) \ Package \ 00067DDF <DefaultPatrolHorseLinkedRef>
3. View the references tab at the bottom, go through each entry.
4. Set Filter by Name to "pack".
5. Change the DefaultPatrolHorseLinkedRef reference as per hotrack's instructions:
    [00] Skyrim.esm (7CAB85A9) \ Package \ 0001A733 <DefaultPatrolLinkedRefNoConvo>

 

hotrack's instructions could use some clarification considering there is no DefaultPatrolLinkedRef, nor is there a DefaultHorsePatrolLinkedRef package. But the basic idea is there, so it's fine I guess.

 

Also, some things to keep in mind with this issue:

1. Not everyone has this problem. This suggests to me there is still a 3rd party, and the combination is the problem.
2. The Populated -mod series also causes similar crashes for some people, yet it does not appear to use this DefaultPatrolHorseLinkedRef package. So whatever that 3rd party mod is, its probably causing more than one problematic combination.
