@bben46's post: Yeah, that might be true in theory, but unfortunately I experienced something else in the past. I don't recall the exact circumstances, but verifying the game cache definetly messed something up in my modded game (~100 at that time, mostly smaller mods, just a view bigger ones). At the end a had to re-install everything from scratch and did that again every time I ran into something not solvable by just un- or reinstalling mods. You can only enable/disable mods with a .esm or .esp file. Those replacing something like animations, textures, meshes etc. work without a .esp/.esm file. And yes, if you remove every single file that belongs to the mod you should get back to a vanilla state. But since you used a FNIS mod, but didn't use the FNIS tool, I guess you already have your solution.
