Good but can no longer progress – DEAD TRIGGER 2: Zombie Games Review

So the game is great but, there is a mission in game which makes the game crash every time. The mission is Can’t Touch This in the China campaign. After completing the machines gun segment the first created zombie comes and destroys something, which causes my game to crash. Please help fix this, thank you
