Im sorry for making such request, but I do really need the gardervoirite but I didnt read the guide carefully enough so I submit the Tauros instead of Miltank. I have heard that if I want to get gardevoirite after this I would have to pay 200 PvE coins which I cant afford even in a long term of time. I'm a new player and I cant really do anything about it so I will be so grateful if you guys can help me to reverse the quest again so I can get the gardevoirite for the team, this means very much to me. Thank you a lot.
