Actually, 1 sim of mine have had used the young again potion. The game went well until the triplets were born. Everyone stopped aging even when "enable aging" is enabled. however, the sim that has used the "young again potion" continued to age normally. I have tried resetting and restoring defaults, but neither of them worked. This is the first time that I encounter this kind of problem and i would want to know if anyone out there has the same issue with mine.
Please kindly note that I have Late night and Generations installed.
