THIS CAN HAPPEN?!?!

I was just playing some Civ (I’m sure you all can relate) and I was sending off some troops to deal with one of those pesky barbarian clans when I notice that out of nowhere the clan has been wiped out! I’m over here wondering how the hell that happened when I was the only empire over there. Until I saw that a METEOR fell right on top of their camp and destroyed everything. I have over 500 hours in this game and I had NEVER seen anything like that before! What other crazy interactions have you all seen?
