I have HORRIBLE connection to the internet so i often lose connection, during one of these connection losses i was feeding a pet, i gave it snack and hit finished, i was taken back to the pet screen and i noticed the same pet had the finished icon on it, so i clicked on it, and i saw that the same snack i previously fed it was still there, i realized that snack didnt have the stats i wanted so i gave it a different snack and when i finished feeding it, it still had the finished icon. A few minutes later when my connection returned my pet got double the xp from training and both snacks xp when i had only trained it once
