I had a similar issue, but I found that if I quit to windows, then started a new game from scratch, the problem seemed to magically vanish.

That was weird!
For now I resolved it by going back to 12.4.1/66.2. I did however merge most of the xml/sql changes from the newest update in as I guessed they weren't the cause. Anyway the problem didn't show itself this time - all other mods were left untouched.
