Help with frequent CTD

[girmrad]

Yes, you are right. I was not running the game. Also, I didn't realize that you had sent me a PM. I sincerely apologize.

[traison]

If it looks too complicated, just go by the assumption that you have a mod with a dll messing with things. The snapshot would only provide proof of whether or not the function was modified by something - we still wouldn't know what. The only thing the snapshot would do is potentially save you some time in case the function was not modified.

[girmrad]

You're right, I was not running the game. I did not realize that you had sent me a PM and I thought you were referring to your message posted here. I sincerely apologize.

 

I have now (I believe) correctly gotten the chunk of assembly from x64dbg. I have attached it.

[traison]

Yup, looks much better.

 

This is interesting, yours is different. Wonder why.

 

Edit: I wonder if mine was patched and yours wasn't. A jump could indicate some mod relocated code elsewhere where there was more room for modification. You probably have the original code.

 

Edit again: Yeah mine's definitely been patched, no question about it.

I see two non-conditional jumps in my code, but they both stay within that function. I'm guessing there's no way to tell what mods / DLLs are injecting into this region?

[traison]

Without bypassing the debugger traps and DRM, no, not that I know of. I did some comparison between our plugin lists and you got all the ones that seemed most likely to be poking around in this area: engine fixes, bugfixessse, skee64.

 

I compiled a list of mods that I have that contain dlls. Maybe see if you have version differences:

Is there a way in MO2 where I can get a list of my DLL mods?

[traison]

Data tab on the right, all dlls are in SKSE\Plugins\*.dll. The mod where they come from is conveniently in the Mod -column.

 

Edit: If some of those mods I listed are hard to find or just gone, I have everything archived. I'll get links upon request.

Edited May 30, 2023 by traison

[girmrad]

OK, so just to be sure, I should install all those mods you listed? Should I downgrade the ones that I have more up-to-date? Should I uninstall DLL mods that you don't have listed?

Edited May 30, 2023 by girmrad

[traison]

Technically any mod could be responsive for the patch, even the ones that "obviously" have nothing to do with this such as Aurora Fix. I would personally start with the ones that look most like they'd be involved, simply based on the names and/or mod descriptions. A patch may have been removed in newer versions; so say for instance you have a newer verison of Engine Fixes than I do - that could be an issue.

 

I really have no other advice than to test, starting with the most likely suspects.

 

I'd imagine you can (and should) restore your mod setup after each failed attempt. You probably don't want to have mods installed that you do not need, or old versions of mods that will cause more issues down the line.

 

Other mods that may be involved as well that weren't listed above: ENB 448 and SKSE64_2_00_20. I'd leave these for last, these really are the most unlikely ones.

Edited May 30, 2023 by traison

[girmrad]

OK, I see. Well, that has greatly reduced the number of potential mods for me to test though.

[girmrad]

So, I was looking at the newer versions of FSMP and it lists having the mod "SMP-NPC crash fix" as a requirement (which didn't exist when I installed FSMP originally). That mod's description says that starting on FSMP version 1.50.4 there is a random CTD when NPCs have SMP hair. Naturally, my FSMP version is 1.50.4. So, maybe that's the issue?

 

Edit: Never mind. Apparently 1.5.97 doesn't have this CTD issue.

Edited May 30, 2023 by girmrad

[traison]

1.5.97.0 definitely has the SMP hair crash thing. That was a thing back in LE as well. Whether the dll fix works on 1.5.97.0 is another matter though. Fastest way to test this would be to disable SMP, if the crash goes away you got your answer.

 

You already mentioned you did this however so, I'd say you do not need that dll. Not for this particular issue at least. Someting to keep in mind for the future perhaps.

[girmrad]

I updated FSMP, updated More Informative Console, and uninstalled Sexlab Survival (I wasn't going to use it anyways). I then zoomed around the world map for a bit and haven't crashed yet.

[traison]

If you want to be sure, you can redo the snapshot thing and verify your function now looks like mine.

 

I redid the snapshot here as well, now including the patched spot (at lines 175-179) which I missed earlier. If you have a jmp instruction followed by 4 int3's where you used to crash I'd say you're good to go.

 

Edit: Keep in mind that if you jump to your previous fault address with the patch applied it will land you in the middle of the instruction. Because of the way assembly works this causes a weird artifact where the instruction you landed at changes when you move your cursor away from it. So, to put that in another way, after you jump to the faulting address, press arrow up or down once until it changes (x64dbg will figure it out).

[girmrad]

I don't see that on my new one.

x64dbgout2.txt

[traison]

That is identical to your previous dump, no patch.

[girmrad]

Do you mean the SMP CTD patch? Yeah, I didn't apply that patch seeing as the creator said it wasn't needed for 1.5.97 and others were reporting issues when installed on 1.5.97.

[traison]

No, I meant the mystery patch visible in my assembly dump. It's not in your recent dump, and your recent dump is identical to your previous dump.

[girmrad]

Ah, no I have not found what is causing that difference yet.
