Thanks!
Yeah they get lost places too. I've lost them on WA holidays before, simply left behind or at community lots. More poor coding I spose.
Fixed this family - I found a clue in a second thread on the same topic here - something like "MM stuck in inventory". I don't think of these as MMs I suppose. I put a second (well actually fourth) car parking space outside the garage, since it occurred to me that the garage parking space might be blocked. Sent the teen to a community lot, and when she came home she parked in the new space in front of the garage.
I actually stopped getting MMs because I lost so many. Maybe now that I have ONLY the mods I want, and those good, I can actually PLAY this game the way it's meant to be played.
