@Anex: Thanks for clarifying that it is legal to cade this spot like so. I just wanted to be sure.

@Rosie: I haven't been able to test if the door will auto close when blocked, but the door may jam and then it would be truly glitched.

@xenofei: You say it's unbreakable and/or and unfair for the zombies, but the cade is breakable with enough zombies spamming the door and pulling the props, it's happened to me a few times.
