Have you checked the patch hasn't reset the falloutprefs.ini? 'yeah i even deleted them and redid them. If you make the same Fallout.ini edits to your Fallout_default.ini (located in your Fallout New Vegas directory, the one with the FalloutNV.exe) archiveinvalidation invalidated will work again. better explaination here

Yeah having the same issue. Was working fine until about an hour ago with the new patch. I have a solution! My fallout.ini was being rewritten by the default version every time I started FNV. The solution is: exit Steam (don't know if necessary, but I did anyway) make your Fallout.ini and FalloutPrefs.ini edits open your FNV folder (with the FallouNV.exe) make the same edits to Fallout_default.ini that you did to Fallout.ini save Fallout_default.ini profit. After this Archiveinvalidation Invalidated worked for me :D
