Egg Issues!

I have had two 2km eggs hatch at different times (not back to back) & both times the screen had froze on the "oh?". After restarting the game, I go to back to check what hatched & theirs no brand new Pokémon, as Im pretty aware of what Ive caught in recently, compared to something hatched, so idk wassup with that?
