Are you breeding them in a vanilla forest biome?DW20 pack on 1.4.7. Trying to breed Heroic Bees. Any hints? I've got Steadfast and Valiant breeding in an alveary, three frame housings with chocolate frames, two mutator blocks with uranium in. I've bred them about a dozen times, and not got a single Heroic or any other mutation. What am I doing wrong? Do I need more mutators?
