Apart from you answering "5" years too late now, this wasn't even the problem to begin with.
This one was a prime example of what happens when you mix up the only sanely advisable approach to Archive Invalidation, = BSA Redirection, and the archaic, outdated, and never working reliably to begin with approach based on the manual or automatic entries into the file called "Archive Invalidation.txt" at the same time.
BSA Redirection will make a different BSA file the only one requiring Invalidation ever again, and as it's an "empty" dummy will remove the very need for Archive Invalidation itself once and for all, and still having entries inside the "Archive Invalidation.txt" file will instruct the game to use external file X over internal file X found inside the now-empty (remember?) dummy BSA, which is known to cause multiple random issues.
Especially having this file point to resources previously removed again will lead to "forcing" the game into a missing mesh/texture error, by forcing it to use a file which doesn't exist anymore.
I'm not repeatedly telling everybody asking about Archive Invalidation to just get rid of that file "Archive Invalidation.txt" under all circumstances and only apply BSA Redirection once and then forget about it for no reason after all.
