Your Lily isHi - first time playing and my growth serum's don't seem to be having an effect - was wondering if someone could help me? I have been giving staff the serum to increase height (particularly in marketing), which says it should occur by 1 inch per day, but no one's height has increased in their character details. Also not sure WG and BE serums have had an effect but they are percentage chance per turn, and I've only just unlocked BE and WG I understand is a slow process.
I have used most cheats as I didn't understand the game at first, don't know if that will have caused an issue (although I'll be giving it a clean run through on next release!)
I have attached a save file (but never done this before either so not sure it is the correct format!)
Since your save isn't quite as progressed I used mine to test the other traits. I know the breast stuff works from experience.
I also made a 10 turn (=2 days) growth serum and gave it to Lily (yours are all 3 turn duration) and she grew by two inches.
Try giving them the serum overnight and see if that works.
