WOW I am super late to this party, but i found the solution to your problem because I just solved it not five minutes ago after finding this post. SO here is what i did. In your archive section of the SkyrimEditor.ini you will find SArchiveList=Skyrim - Textures.bsa, Skyrim - Meshes.bsa, Skyrim - Animations.bsa, Skyrim - Voices.bsa, Skyrim - Interface.bsa, Skyrim - Misc.bsa, Skyrim - Sounds.bsa, Skyrim - VoicesExtra.bsa, Skyrim - Shaders.bsa so i added , Update.bsa, Dawnguard.bsa, Hearthfires.bsa, Dragonborn.bsa after the Shaders.bsa. Then in the sResourceArchiveList2 part the hearthfire.bsa was giving me problems so further looking i found it has to be HEARTHFIRES.bsa so it would look like this SResourceArchiveList2=Skyrim - Shaders.bsa, Update.bsa, Dawnguard.bsa, Hearthfires.bsa, Dragonborn.bsa That solved the problem for me I hope it helps you if you are still looking for the answer 5 years later. Or if anyone comes to this post i hope my answer helps This fixed my issue that and adding in the bAllowMultipleMasterLoads=1
