That's weird. DId you look in SimPE to see if she the doppelganger has a character file associated with her ?
Not bothered with SimPE yet; might pop in tonight and take a peek.
Have never moved an occupied house into the bin so I've no idea if that would cause a similar issue.
Given Zoe-in-the bin cannot be moved anywhere or played, it may be more more interesting to just leave her there and see what happens when my playable Zoe is visited by Grimmy. A tombstone in the bin??
