Hello, I connected to the game today and I noticed that some of my items are missing. My only master ball and all my rare candies (more than 110). Maybe more re missing. It's obvious that someone stole from me so I changed my password. But I would like to know how and wh it just happened ? I gave m password to no one and I know nobody from the game. I also ould like to know who didthat, so the person can be banned. And eventually get my things back. Because this is so unfair. Hours of game for that... It should be fun, it should be nice. Thanks in advance.
