I have a theory about this one, as it happened to me on my 2nd village, where I stupidly left the Dino Den out.

I think it has to do with the freeze. You are going along merrily tapping and trying to chain when the freeze happens. If you happen to tap on the DD you'll bring up the buy a dino screen. If you tap again during the freeze, the tap is kept is some sort of buffer. Hey presto!, you've bought a brand new dino egg and hasta la vista crystals.

Anyway., that's my theory. Maybe I can become a professor? But no stones please! Doesn't suit.
