A few months back I had a new HDD installed and had to reinstall F4 and NMM, However I could not get the game to run at all despite re-downloading the mods I used before (CTD on loading a save). Yesterday I got the backup off my old HDD of the Nexus folder and the Fallout 4 folders and just copied them into the new game folders and the game worked, with all the old mods running. I played for several hours yesterday in one session and was happy! Today I fire up the game and once more the save from last night CTDs. I am stumped. Why would this be? Mod list and order: ArmorKeywords.esm SpringCleaning.esm More Where That came From Diamond City.esm OCDecorator.esp dD-Realistic Ragdoll Force.esp TrueStormsFO4.esp SpringCleaning_GrassDirt.esp SpringCleaning_SancConcrete.esp CraftableAmmo.esp CraftableAmmo_plus.esp When I try to launch yesterdays saved game I get the error message: $LoadVanillaSaveWithMods To me this suggests the save from yesterday was played without mods... but it wasn't. Please help a very confused noob. Thanks.
