They both drop super fine white wool, when I believe the alpaca should drop 'fine white wool' instead.
Copied and pasted description from discord:


Both starter rabbits and alpacas drop super fine white wool when sheared, which is a problem because it means that fine white wool (without the super) cannot be obtained, so all alpacas cannot be unlocked. Presumably fine black wool drops from an alpaca that cannot be obtained as a result, so the wool skill tree cannot be completed. I am assuming starter alpacas are supposed to drop fine white wool, not super fine white wool, as the black rabbits drop super fine black wool.
