@floridameerkat Yes, i was just playing it. Sorry, i'll explain.
I've set lifespan to short and started playing. I have no idea how many sim days i've already played but i know that my sim aged to adult 1 or 2 days ago.
I was setting some stuff in mccc and saw in the mod that it was possible to set custom lifespans for each age group. So, i've changed the lifespan. I've set adult lifespan to 12 days.
When i got back to the game i saw my sim will be an elder 5 days from now. Because my sim aged to adult 1 or 2 days ago, it seems that the lifespan is 6 ir 7 days...?
So, i've read that adult lifespan is 21 days, i've set it for 12 days in mccc, and the game gives me 6 or 7 days...
