I've run into an annoying (but not game-breaking) issue. Currently I'm working with four YA housemates who swap ages every now and then. I know there can sometimes be age glitches if a Sim gets a tattoo or if the player goes to Create/Edit-A-Sim but I've done nothing out of the ordinary with these Sims. The glitch happens when I save, quit and come back. When I save and quit, they are in ABCD order. When I come back, they are no longer ABCD and there's no consistency as to what order they turn up in. My only clue that they've swapped is that their left-screen portraits have switched places to reflect their new ages.
No one is significantly older or younger, just a few days. It requires that I am super-diligent, however. Every time I fire up this file I have to be sure I'm issuing instructions to the correct Sim. Otherwise, my gardener will end up fishing and my painter will attempt to fix the broken TV (ahhhh disaster in the making!).
Has anyone else encountered this and, if so, do you know a workaround?
