I was playing the map and on round 39 the game closed and this message appeared: "gspawn no entities available" or something like that. Ithere any solution for this error message?

Guys I found a glitch that allows you to get to round 0. On that round no zombies will spawn. It's pretty tricky to do. It's not a gamebreaking one and it can actually help new players getting to know the map. I've posted it to my youtube channel. It's up to you if you want to delete it or not.
