I am pasting a link to a thread that I started almost two years ago about the same issue. My lock is S&G, by the way. I have stopped spinning the dial and I have not had a problem since, using the original combination.
https://www.24hourcampfire.com/ubbthreads/ubbthreads.php/ubb/showflat/Number/15656745/This is fortunate, because I e-mailed Fort Knox about the issue, and I still have not received a response.
Hope this helps.
