Immersive Cleaning uses rebuilded Precombines for the settlement to scrap the things. So it's not compatible with all mods, that edit or replace the precombines.
No BostonFPSfix (flickering at University Point) no Beantown Interiours (flickering at red rocket) no South of the Sea (Flickering murkwater Construction) repeatable crashes near quincy (vault 88 entrance).
I use Scrap everything again. It's bad for the performance (except downtown Boston) but it's compatible with nearly everything, as long as you are carefull what you scrap
Hey Kingath, maybe u could make a better scrapmod :D
