Ooh so you had a chance at getting the "body" of one but not always? Makes sense why my merino x cow blend always came out with no body modifier :)
Yep, it could also mean that no matter which combo you try, you just get one of the exact same that you put in. In hindsight I should have made it so you always get a mix, but for now it is like this instead. Just body 1 or 2, and fur 1 or 2.
