The Crew-Mium is one of the items that we need to collect for the Japan Pre-Release event. Yesterday it had stats of 259/300 and today the stats are at 0. The item probably helped some players when it had stats but Zynga had to shut that down! It was most likely a mistake since the crew related item in the previous pre-release events didn't have stats either. It wouldn't have killed Zynga to just leave it alone. There are bigger and better problems in the game for them to worry about!
