Not that I'm complaining, given that I looked all over PokeHeroes
and found as many eggs as I could reasonably expect to find, but
did I do something wrong in accepting the gift?
You only needed 12 out of 20 for the event egg. The 18 out of 20
was for a special extra gift. I hope this helps. It says it in the
Easter Event by the way, so you might have just misread it.
Edit: I just reread the event page and the post, so now I am
confused on what they meant.
