From the FONV Mod forum: http://www.gamesas.com/index.php?/topic/1139267-archiveinvalidationinvalidated-broke-again/

Thought I would post this here and might save some grief ...

If you update to the new incremental patch and use Archiveinvalidationinvalidated! then you must re-edit your Fallout_default.ini file as follows:

SArchiveList=Fallout - Voices1.bsa, Fallout - Sound.bsa, Fallout - Misc.bsa, <>, Fallout - Textures.bsa, Fallout - Textures2.bsa, Fallout - Meshes.bsa

The Archiveinvalidationinvalidated!.bsa must now come after Fallout - Misc.bsa and before the textures and meshes bsa's ...

thanks for the "warning" here too, havent heard from this before but this is good to now!

It works for me just not having it listed first in the list. Like this:

SArchiveList=Fallout - Voices1.bsa, ArchiveInvalidationInvalidated!.bsa, Fallout - Textures.bsa, Fallout - Textures2.bsa, Fallout - Meshes.bsa, Fallout - Sound.bsa, Fallout - Misc.bsa

I just moved "Voices1.bsa" to be the first item in the list.

Somebody mentioned only renaming the ArchiveInvalidationInvalidated!.bsa to ArchiveInvalidationInvalidated.bsa works for him without any changes in the loadorder.
could this be, only the "!" in the filename ist the problem?
