For everyone having trouble with archive invalidation and the new patch here's how to get things working.
Short and sweet:
1) Rename your the fake BSA to - "Fallout - ArchiveInvalidation.bsa". Update the ini files to reflect this change. This will allow the fake .bsa to be the first on the SArchiveList entry.
2) Change the order of the .bsa files in the SArchiveList. Put Fallout - Voices1.bsa" as the first entry, then the fake .bsa [Fallout - ArchiveInvalidation.bsa], then the rest of the .bsa files.
