Can anyone verify this? I think that she takes the most recent item (the one lowest and right-most in your collection). I've found that I can move stuff from the front of the list to the back and she'll steal that stuff (one-star crummy animal stuff) and leave my true prizes alone.
Haven't gotten a total verification on this.
I've tried that in the past and it doesn't always work.
It worked every time until I posted. Then it stopped working. Go figure.
Tonight I had a game where she stole something I really like (the Gong, I think). I had hyperspace, so I immediatly traveled to every homeworld, found it, and bought it back.
