Good game but.. – 100 Floors Zombie Escape Review

Every time that I place a mine I front of me and a zombie explodes a zombie on the map becomes invisible and it is really annoying that I am about to finish a difficult level and I get eaten by a zombie that is not even on the screen. Please do fix this j love this game but it is not fun anymore when you die by something you literally don't see. Other than this I love the game but please fix this.
