Hi, I used to be much more active but still log in occasionally. I logged in today for the first time in a while and the only Pokemon I have are some Unown, even though I used to have many Pokemon, including some level 100 that I had trained up or traded for. I don't know if this is a bug or if my account got hacked, but I don't share my account or password with anyone. Is it possible to get help and get my pokemon back, since I'd like to keep playing? Thank you!
