well it doesn't ..i haven't purchased eco living but i have read countless threads regarding the bugs ...lets hope they do a bit more of fixing with updates on eco living but in the meantime...you can choose to start a fresh game..before you play it go to game options and turn n.a.ps off then in your game use the cheat window and use ..testingcheatsenabled true and then shift click on the mailbox to set up the naps you want active ...there is a few that cause the least amount of issues. i want for someone to agree that the cheat to click on the mailbox for setting up naps is correct ..i don't have that expansion pack as i said and this is all from memory of how to fix ..but apparently that works so you avoid the more troublesome n.a.p.s like sharing is caring.
