I've used this mod in the past to great effect. With several occupied vats, skills would grow at a consistent rate for children in vats and the given skills/traits would be varied. However my recent experience using only 1 vat was highly differed.

I think I encountered an error. I used 1 of each machine on 1 occupied vat at once. The baby had 20 in both Melee and Shooting skills at age 3, but then her Social skills only improved by 2 levels until she was 7 years old. At which point I only got 1 trait to choose from and no passions on her growth moment. I don't know if this was a bug or I just did something incorrectly. Please advise?
