I have never heard of this bug and Google is not helping so far.

Have you tried warping to another area first and returning to the crypt?

Which console are you on? Are you on PC? If so, I believe there's a way to make a backup of your save file. Unfortunately, by this time your current save file already has the bug in effect and probably beyond repair, but keep it in mind for future playthroughs.

The only thing that comes mind is that there's a slight possibility your video card (again, if you're on PC) is the one causing this issue. I don't know, perhaps Vendrick clipped through the floor or something. Try to update your drivers and give it one more try.

Please, let us know how it went.

Regards.
