On the door, check Dynamic Path

I've checked. Everything is checked DYNAMICPATH is checked also. I've watched JBird632's tutorial how to implement a debris into a map.

Ok. Sure I will try that !! Thanks for replying !!

The problem is that, If I get to the power-room, zombies aren't going through that doorway. I've linked screenshots from the editor and a video presenting the issue. Please help Any help would be appreciated
