When one of my child sims does the Artistic Prodigy aspiration, I always leave the "Play musical instrument for 5 hours" for last.
Because they'll have maxed Creativity by the time they reach that goal, they can get mentored and earn about 5 levels of either Violin or Piano.
I'm sure many of you approach this aspiration in the same way.
With my current twins, the first one completed Artistic Prodigy with a Level 5 violin skill.
The second kid, however, maxed Creativity then played piano for five hours without earning a single point in that skill.
I tried having the kid quit playing piano then restarting to see if he would acquire the Piano skill, but he never did.
Has anyone else experienced this same issue?
My previous generation (two kids) both maxed the Piano skill as children, so this glitch is new to my game file. Like, post-patch?
