I have that set to 0 but I am also getiting CTDs in Sanctuaryfor the last week also but for me it seems to be several items under the power category. Deleting , building or scrapping conduits the siren for attacks,, pylons or vanilla generators causes a CTD Other items may be affected that I haven't checked yet. Using disable via console will remove them items not sure if that causes any additional problems I did build a power generator from another mod and was able to connect some newly built items to it. Connecting to pre-existing pylons or devices caused a CTD. There are still some things like the siren I cannot build at all though without getting an instant CTD.
