I am not to fully sure were I am able to placw this but dueing the epic breeding event I wanted MC Boss but after it was done I got Saquach....I checked if this was a mistake and I am not sure if hes even breedable. I have screenshot proof but ya Im not sure if this is a bug or just a monster they forgot to add as breedable...

@jared-renteria during epic breeding you can get the target monster but also other breedable and unbreedable epics prob some rares too
