Major flaw in contested territory

Had to stop this game after the multiple crashes while playing Contested Territory. After spending 2 hours getting to high levels the game just crashes and you lose your progress. Seems to happen when the events are refreshed, I find it to be extremely rude and now regret giving the game developers any money. Dont waste your time on this game.

Stay away for your own good about Bloons Monkey City, v1.11.2
