  A simpler solution is to adjust the accuracy of the normal calculations.
This is done by adding the keyword 'accuracy' to your normal block
followed by a small float (try things like .01 and smaller).
  The normal calculations have changed a bit from 3.1 to 3.5 but adjusting
the accuracy will usually give you the same result as in 3.1.
