Let me clear again.
If you use cheat and raise Strength to 10..it wont work. real you maybe was on just 3 or 2.
so no help with Ivy. she are at 10. one Pills give you 2-3 strenght plus so need 3 time pills. if not help then try mod and turn strength back to 3 and try with again pills 3 time.
if no help ouch! then you have to start again and dont use cheat with Looks,Charm,Strength and Hack.
Keep and keep with this list.
Charm and hack :read and learn on room. ( can raise charm with pills).
Looks : sunbed relax alone tanning. maybe with beauty cream(not sure).(can raise with Hair gel)
Strength : traning with Jennifer or alone. ( Can raise strenght with pills).
all this thankful and help from other tips to me. it works.
