I'm not sure if you fixed it, but when you first posted this map I downloaded it and the kill barrier behind blue spawn didn't work. You have to make the barrier wide, tall, and long enough for a person to fit inside of it for it to be able to kill a person. It will kill the person only if they are completely inside of the barrier. If it's a soft kill barrier, you will need to make it much bigger on the side that isn't in the map, so that they can't run all the way past it before the 10 second countdown. I hope this helps.
It is fixed has been for a while check out the new version its here some where in the posts Added after 1: Check the second page and you will find the new version all has been fixed
