Hey there, I got this bug i think that my Ivysaur level 17 became a Bulbasaur level 5 after I relloged in my account. Unluckly, I don't have a print screen of my Ivysaur but here's a print screen of Bulbasaur level 5. I tried to close the game and open again, switch the servers, get some xp with Bulbasaur but nothing changes. And it only happened with this single pokemon, the rest of my team is basically the same. I'd be grateful if you guys could help me
