Random ages

I seem to remember some aspect of a MOD, maybe it was MCCC? or UI Cheats?? that randomizes sims ages during their lifespan so everyone wasn't the same age in a new save? Since I use MCCC story progression, all the premade townies will age up and die at the same time which is kind of annoying and predictable. Let me know which mod randomizes the ages within a lifespan. Thanks!
