So I've been having some trouble with bees lately, in the fact that i've been trying to breed Corroded and Tarnished bees together to get myself some Resolute bees, mainly through breeding bees in alvearies, injecting them with serums to make sure that the only thing that doesn't match is the species, and even using three mutators in the alveary. After about a stack of uranium and even a nether star, I've still only managed to get corroded-tarnished mixes. Am I being dumb or is this a bug?
