hello ive let someone ev trained my treeko and afterwards i got it back with the same stats as I send it to him and im sure he didn't scam me since he sent me his stats as he progressed and i think it may be a bug i really like to know how and if i can fix it without ev train him again. 

did you do a lending trade?

yes i did

 

That's why, when you do lend trade, the person receiving the poke can change stuff but when it comes back to you it will revert back to before lend. 

 

For ev service, do regular trade, but always make sure to take screenshots of the pokemon, specifically the ID # on top. And also take screenshot of the chat for proof if ever needed. And add them as a friend 

thanks

Locked as resolved.

Have a great day.
