edit: Also works for compatibility with the current version of the game (which really shouldn't have ever been an issue, but is because Bethesda.
This works fine for any scrap mod, not just Spring Cleaning. It triggers the game engine to disable combined meshes and preculling in the cells that make up vanilla settlements, so it will let you scrap anything you have a recipe for in those locations, no matter if those recipes are from Spring Cleaning or any other scrap mod.
Installation:
1) Install with NMM or place SpringCleaningCompatibilityPatch.esp in your Data folder
2) Load this after any mod that touches a vanilla settlement
I recommend you install the ini version (which uses a esp version of Spring Cleaning, and doesn't reference any cells), then delete SpringCleaning.ini from your data folder.
You can instead manually install the esp version of Spring Cleaning (in the optional_ini version folder) instead of the esm (or delete the Worldspace category from SpringCleaning.esm), as it has way more Place Object references than needed (bad for compatibility, if another mod moves those references), and my patch makes them redundant. Also, I have seen claims that it undoes some some changes made to the airport by the Automatron DLC.
