Hello, my in game name is Ozychlyrus and recently I have been doing a lot of breeding. Every forty minutes I will check my breeding plot and get an egg. About a half an hour ago however I grabbed an egg from my breeding plot and the egg replaced/deleted the pokemon that I had in my first party slot. This pokemon was my strongest/ favorite, it was an Articuno. I do not have any screenshots of the Articuno that I know of, all I have as proof is my completed frozen shrine and a few people that have seen the Articuno. The Articuno knew Fly, Roost, Dry-Freeze, and Hurricane. It's IVs were at 87% with 3 perfect. Is this a common bug or a bug that is being worked on? If so please let me know. Thank you for your time.
