Ok. Lets get this straight I got a eevee it even appeared in my inventory but 2 sec later it left and said it was so close I caught it and then some other guy caught it I'm very mad please fix this and maybe get me a free eevee because I'm not waiting this long for another to appear. please I want that eevee and I didn't get it so please.
Sorry but you can't receive that eevee back. Also you should have taken a screenshot of when it escapes for proof. But you find another eevee easily if you join the discord. Everyone reports any rare pokemon they find: https://discordapp.com/invite/pokefind
