Mod Tuning (I guess, idrk)

The issue sounds like you're using outdated mods rather than random conflicting mods, especially because nothing happened before the patch. There is a list of updated/broken mods here, please go through it and clean out your mods. Unfortunately, there is no way to quickly check if a mod conflicts or not. You just have to remember what mods you download, do the 50/50 (either the normal way, or with an override folder), or open each file and check. Or even go back to the download pages and note what the creator says. There used to be a conflict detector but it hasn't worked in years, and random mods that don't conflict are flagged all the time. Like an outfit override for Father Winter was flagged as conflicting with a pancakes recipe. Completely unreliable, lol.
Anyhow, if you do encounter mods that are actually altering the same files for different reasons, please follow this tutorial.
