So....say I have an angler for a founder and a couple gens down the road, I have a scientist, can the scientist use the other two certificates (handiness/gardening) for their career rewards, even if they have to max fishing for the career as well? Or is only one heir allowed to max it? Because I honestly don't see what the problem is if two heirs max a skill for their job, IF the skill certificate for said overlapping skill is not used for a career reward.
