I've tried googling an answer for this but its really hard to type the idea into a search. I have a mod that has an interior cell that i'm working on but i also made modifications to the exterior gameworld and, accidentally, some changes to other interiors. How can i restore everything to vanilla except for the one interior that i'm working on? I also have a few scripts I want to keep, but outside of the scripts and that one interior I want everything back to normal. Can anyone point me to a tutorial or maybe some creation kit feature i'm unaware of to accomplish this?

Thanks. I had used TES5 for cleaning other peoples mods I've downloaded but didn't know it could do that on my own mods.
