I was thoroughly enjoying the game until I had a Gurdurr that I wanted to evolve via trade evolution. He was going to be my strongest pokemon when evolved but he received an IV re roll so worsened, lost CP and was unable to be traded back. Only being able to trade pokemon once is the STUPIDEST thing you could add to a franchise which heavily involves trading. I am very annoyed as I just lost hours of work and I am debating uninstalling. Please fix the game
