Slow it down, Sims!

[Crimson Hollow]

This is a problem about how fast a vampire Sim level up in a skill, and how to slow it down.
So currently I'm playing a sims family with a vampire child, and I realized that child can master a single skill in roughly 4 sim hours.... Which gets pretty annoying because I am enjoying the process the sims build up their skill and this fast learner is making the game rather dull.... Is there any way to control their learning speed? Thanks!

Hi there! Take a look at NRAAS mods. They have multiple mods to customize the game how you want it. With MasterController you can also set the skill level of your Sims. Hope this helps :)
