My game I played as soon as the beta preview came out I played again after the bug report. My nicheling who had purr snout had suddenly had derp snout. It shows in his appearance and in the genetics. However, when you go into the family tree, you can see purr snout listed as his dominant head gene. Also, blood clotting. Some of my nichelings have no blood clotting or they only have recessive blood clotting. So this is what I've found so far and I'll keep looking for more if there are any.
