Players Cheating on Maps

So on a few infection maps players are taking advantage of missing or incomplete soft kill zones on Anchor 9 DEADSCREAM9 where a player jumped on my head, and got to a platform that otherwise can’t be reached as zombies, and second on Downlinked where there is a fully incomplete soft kill in the 0G area, a player jumps on a platform then gets to the highest point and survives. Can you fix this?
