Mod Constructor - multipliers
I see that separate trait buffs will stack multiplicatively.
Testing it for Young Adult Sims:
3 traits for Young Adult Sims and up/older... For example, 2 to the 3rd power is 8x mod, and 3 to the 3rd power is 27x mod. Using 0x will stop. Using 0.1 to the 3rd power will make it 0.001x mod.
