Recently I'm having a problem with voices randomly changing, and it's only happening to sims that age from child to teen. At first, the teen would have voice #1. Then after a few sim hours, his voice would randomly change to voice #2, then to voice #3. This bug has been happening after installing Seasons and Generations, teens created before I installed those EPs are unaffected. It's not just happening to my sim, other sims in the town that age from child to teen are also affected by this bug. So far I tried resetsim, deleting cache files, aging the teen to young adult then using CAS cheat to change them back to teen, but the bug still persists.
