As the tittle says azzure bugs don't lay abyss nymph egg even if the probability is 80% . I attached the save game to see for yourself. Follow the 20 cycle azure bug, and you will see whit your eyes. Game version is 312713 but i am sure that in preview build is the same. So no abyss bugs and no radiant bugs
Steps to Reproduce
Feed the azure bugs whit phosphorus. Even if the probability of laying an abyss egg is greater than 51%, Azure bugs will lay only azure nymph eggs.
