So I just had the weirdest thing happen.  I built a town pretty close to a dragon.  It had one of those super life shrine thingys.  I thought I could snake away enough to keep the town from expanding over the dragon until I was tough enough to defeat it. 

I was wrong.  My town was at level 2 and the dragon was set loose.  Imagine my surprise when the dragon dropped dead.  I have never seen that before.  I didn't even try to defend it because I would have gotten crushed!

Has anybody else seen something like that?
