I have a feeling I'm going to be too late to help but I have a solution. It's not perfect but it works. (I had the exact same issue after whiterun siege). In the console type: prid 6a167 (and then press enter) Then type: disable (press enter) Now type: prid 17055 (press enter) Finally type: enable (press enter) This should fix the drawbridge issue with general gameplay, although if you come across any scripts which open and close whiterun gate I can't vouch for whether or not they will work. I hope I wasn't too late in helping but if anyone has the same issue this should work.
