Great white wyrms aren't vulnerable against fire
Great white wyrms aren't vulnerable against fire, and it feels they should be.
Problem
Great white wyrms aren't vulnerable against fire, whereas other white dragons are, and great red wyrms are vulnerable against cold, their opposing element.
How to reproduce it
Attack a great white wyrm using a fire spell or wand. You will notice there's no message about him being badly (1.1.1) or painfully (1.2.0+) injured, nor does he take double damage.
