OK, the first sighting of the Lanterna was at approximately 12:45pm. That means that if the 4 hr "rule" is correct the first time I was on the game was at 8:45a (which might be right). Based on that, the little Lanterna should continue to mock you guys until around 4:50pm CST.
It will be interesting to see when it disappears. So if you guys can continue to occasionally check I would appreciate it.
