I only installed NVR quite recently (on my earlier installation on one of my HDDs). The crash with the Sentinel (and I also assume the Granger, although I did not know about the latter vehicle causing problems at this time) predates my installation of NVR. So, I also think that should be ruled out (although not completely). I first noticed the Sentinel crashing with Scripthook (likely an older version), Simple Trainer, replacers for most weapons, and the RDR physics mod, as well as a blood decal / wound mod. Nonetheless, this was before I installed NaturalVision Remastered. These issues aren't exactly new.
So, if NVR is left out (for now), I have no weapon or car replacers installed at the moment. That leaves them out as well. Simple Trainer does not appear to be a problem either. This leaves Scripthook, and the aforementioned physics and blood mod I'm using.
The current version of Scripthook is frequently said to cause crashes. However, as stated, I've never heard of anyone having cars spawn without drivers as a result of Scripthook. I do get occasional 'random' crashes. I do not know if they are related to the Sentinel and Granger crashes. They may be completely different. So, should I replace some vehicle configuration files with vanilla versions, and see what happens?
Edit: dlclist.xml seems fine. Well, there are two of them (I assume that is normal). The second dlclist.xml in my mods folder has all the appropriate stuff listed, including the three that are part of NVR.
sentinel_mods.rpf (last line in OpenIV.log, which I take was the last thing loaded before the most recent crash occurred) does not exist in my mods folder. It only exists in the regular 'update' folder I believe. Is this a problem? When I install .oiv packages, I always choose the option to install in the mods folder. No idea why this wouldn't have copied to the mods folder as well (unless none of my mods modify it at all). If that is the case, then I guess sentinel_mods.rpf is also not causing some of the crashes? Weird shit is afoot for certain...
I uninstalled the ASI loader to test without any mods (excluding reshade and ENBseries, which were loaded since they are in the main directory, and should be). I drove around for about a minute...and then, sudden crash. Seriously. What the fuck?!
However, I did spot a Granger driving around. For once it did have a driver, lol.
Curiously enough, when reinstalling the asi loader and going into the game again, this crash (which seems to happen between five minutes of loading into the game) stops. Grangers now have no drivers again.
