Need help.

I am glad to hear that you passed the level in which your game froze. You are surely a skilled Farm Heroes Saga player since your signature indicates you are at level 3686. While it is not possible to return boosters used when playing a level (even if it freezes), I encourage you to keep collecting them with the free spins at the start of new levels. I have had my game freeze when my battery on my device gets low, so be sure to maintain plenty of battery life while you play. Keep up the great farming!
