Meanboy, I’m sure someone’s got a better answer than this but all I do is just resculpt that area as best I can when stuff gets whacked out when transposing.
I do find that placing my rotation pivots EXACTLY at the relative skeletal joint of the limb I am moving helps out a whole lot and minimizes distorion.
Good luck.
  
 I’m a total noob when it comes to relief sculpture - I love those coins; they look deceivingly simple but contain so much depth!
