I used to play Modless and that wasn't too bright when I kept getting children being taken away by the social workers and the saves were always getting corrupted to the point that thwy became unplayable or they glitched out after too many sims were made pregnant by the game including sometime getting wrong ages being made pregnant.That was the end of my Mod-free play after the teens got made pregant by glitchy saves and got messed up so badly they were unplayable from that nightmare.I got Mods to end that mess and make the game stay playable as it had too many other issues when played without Mods.
