I gave the VV game to my niece for Christmas and was showing her how to play. We'd just upgraded the big hut to a school when her sister, who was jealous of us spending time on the computer, hit the "hard reboot" button. When we reloaded the game we found that the school had disappeared and the (only) master scientist we'd used to build the school had reverted to adept. Yvette spent an hour at the computer after that waiting for him to go back to master, muttering "I hate my sister" all the while.
