I had the same issue as the others. No matter what method I used I couldn't get the ArchiveInvalidation to take. I tried MO ver. 1.2.4 and it worked just fine. I used the manual version of this and loaded it as a mod into the organizer. https://www.nexusmods.com/fallout3/mods/944 I edited the Fallout.ini, Falloutprefs.ini, and the Fallout_Default.ini as follows: [Archive] SInvalidationFile = iRetainFilenameOffsetTable = 1 iRetainFilenameStringTable = 1 iRetainDirectoryStringTable = 1 bCheckRuntimeCollisions = 0 bInvalidateOlderFiles = 1 bUseArchives = 1 SArchiveList = Fallout - ArchiveInvalidation.bsa, Fallout - Voices1.bsa, Fallout - Textures.bsa, Fallout - Textures2.bsa, Fallout - Meshes.bsa, Fallout - Sound.bsa, Fallout - Misc.bsa I also went ahead and made my MO folder writable. Now I have the bodies and the textures just how I want them.
