User blog:BonesMcGee/"Testing Pred" Challenge? Free Dimetrdon? Huh?

That was weird... So I"m only lvl 34 and I just received a challenge to build the Great Pyramid in my scrollbar. I clicked on it, and it took me to the task list which consisted of no text...just a picture of a tree chopper with a "completed" check mark beside. Then the success/reward screen popped up with the text "Testing Pred" as the title. The reward was a dimetrodon, and now I have a dimetrodon egg in my inventory. Huh? What just happened? Is Matt Fairchild messing with me?
