I've heard some lucky people have had this fixed with the 1.2.33 patch. I'm still getting crashes in the same locations and more.
My original bug is documented here: http://www.gamesas.com/topic/1544248-bug-report-index-pc/?p=24518292
I'm happy to provide save files and videos if asked. Please look into this, the game is currently unplayable.
Edit/Update: I think I've narrowed it down to being in a fairly large radius around Vault 81.
