The adults from the home of the teen adventuring in Egypt, tagged along. While the teens are following adventure trails, the adults are collecting stuff, rocks, insects, relics. They have been having trouble finding dig sites. I've been watching all the common spawning spots, but there is nothing there. The girl doing the smaller adventures, concentrating on accumulating Visa points just sold another tourist brochure photo, getting her to level two and she then bought the 'Tear of Horus'. Now there are dig sites everywhere. I looked in these places only a few sim hours ago and there was nothing. I wonder, does buying the ToH cause the sites to spawn?
