Ostim Standalone crash

[ylt_enes]

Hello, I've loaded too many mods and, as you might expect, my game is crashing, but this only happens when other NPCs enter the scene. This occurs during the sex parties at the ancient profession ostim port. Can you help? (Even if I'm not on stage, the same thing happens when another NPC's sex scene ends.)

It's definitely because of the OSTIM files, but I don't know how to fix it. Can you explain it to me like I'm an idiot?

This crash was indirectly caused by OStim.dll. It has an out-of-bounds read error in it which was set to trigger a debugger breakpoint (int3). This came from trying to parse a json file.

 

Search through all json files in all mods (not including BSA archives) for the following string:

"formid":"FFFFffff","mod":"The Ancient Profession.esp"

 

The formid is obviously wrong there. Fix the form id, or remove the json file.

Yes... Now, could you please explain to me, a complete novice, how to do it?   because I don't even know exactly where to find what you're talking about

 Go to your directory where all mods are in file explorer, in file manager type *.json in the file manager search bar. Should be a start.

Notepad++. Do a recursive search through your mods, filtering for *.json.

 

...or do it by hand like Vortec suggested. You probably don't have that many json files anyways.

I found the JSON files, but I don't know what to do with them (The form ID is obviously wrong there. Fix the form ID, or remove the JSON file.) How exactly do I do that?

By figuring out what the value should be. If the json files belongs to a dildo adding mod, perhaps the actor id should be that of an actor in "The Ancient Profession.esp" that really needs a dildo? Use your imagination.

@traisonI did a thorough search with Wingrep, and everything I was looking for came up, but when I typed that error code, nothing came up. Even when I typed Formid fff, nothing came up. The file might be somewhere else.

@traison Can you help me? I've tried everything, but I can't find the error.

I assume you mean the form id.

In that case don't assume because the file looks like it contains JSON, that the extension is *.json. Search through all files in all mods.

@traison I did exactly that and no error occurred. I even went further and scanned the entire C drive (“formid”:“FFFFffff”,‘mod’:“The Ancient Profession.esp”) but neither that nor the FFFFffff error code appeared. I decided the problem was definitely in the OSTIM patch. There's no problem in Sexlab, but I hate Sexlab. I'll try to reinstall the patch cleanly.

And you have no additional partitions? Mods are all somewhere on C? Are they in a hidden directory? Does your tool search in hidden directories, such as AppData etc.?

 

The bottomline is ostim.dll is trying to parse some json data, and it's failing. Find the json, you find the problem.

 

Other than that, I'd have to see this problem myself to be more specific.
