I think this is the main problem NoBuildLimits.esp , "Completely removes all height and boundary limits on settlements." "The Green boundary wall will still look like normal but you will be able to build past it." This should be your problem as it totally removes Settlement boundaries I hope this helps solve your problem One other thing I noticed in your mod list is that you have all of these Scrap Everything esp's, Scrap Everything - Ultimate Edition.esp=1 Scrap Everything - Core.esp=1 Scrap Everything - Automatron.esp=1 Scrap Everything - Far Harbor.esp=1 Scrap Everything - Nuka World.esp=1 Scrap Everything - Vault-Tec Workshop.esp= The problem that i see is that Scrap Everything Ultimate is all the esp's combined in one . It is Core ,Automatron ,Far Harbor ,Nuka World ,Vault Tec Workshop, all in one , so you should only have Ultimate by Itself without all the other esp,s If you run LOOT to check it will tell you the same thing . Below is the direct quote from the Scrap Everything Nexus page "Can do any combination of DLC. Install using NMM (has a FOMOD) (contains "Ultimate Edition", which is just all the plugins combined into one)" This is probably not directly causing your problem, but I don't think it is helping . Good Luck
