How Do I Tell What Mod Is Causing a Crash?

[PossibleTango]

How do I tell what mod is causing a crash? It was working perfectly fine till the new hotfix. Is there anyway to tell what is causing this and what mod is causing it?

I don't know here, sometimes the crash will mention what it was but i don't see it there. I would check the mods to make sure they are updated to the version you're playing and check the comments in their page on nexus (or wherever) to see if other report bugs. I might start with ones that effect AI party decisions but I don't know which do that.

There was no problems till the hotfix came out. But I have no idea how to diagnose it.

You probably need to check the mods to see if they are updated now after the fix. Probably other player using the mod will report it too.

You have a lot of mods! It's no surprise that your game will crash after a patch. Usually, it's because a mod isn't updated to the version of the game you're using. What I do is, when an update downloads, I either decide to stick to the previous version or get rid of the mods and re-download those that have been updated to the current game version.
I never play with more than 5 or 6 mods at the same time, any more and that's asking for crashes and weird results.
