Sadly, he is right. I got an e-mail back cause I was complaining that every time I tried to catch the War Lepus, the game errored out on me. Their reply was:
We are so sorry, but this Quest is no longer active - we apologize for any frustration this may cause you. Take heart though - you can still enjoy catching all sorts of fabulous Moga's and working to become the best Moga Ranger ever.
