Lag or Bug in the game

The game stick, I can't kill the animals like chickens, sheeps, llamas, horses, all kind of animals. The "server time" is over than 165m/50m or something like that, I don't know what it means, I can't create another thing because when I recharge the game it just desapear, I played this game without problems but now I don't what's happening. It takes time to load and sometimes it does not enter. Please help, I do not want to uninstall it
