This my first time playing VV 1, but I have been playing it for awhile now. My problem is that no matter what I do I can't get a Master Builder or Master Farmer. Two of the original people have passed on after 70+ years. I've completed 9 of the goals, and have all of the upgrades. I've made sure to put preferences on each person, and they have been working their butts off on those tasks. Surely after 70+ years I would have a Master Builder or Master Farmer. Am I missing something?

Very perplexed,

Matt
