There are a number of errors in the level that I can not fix due the fact they are in the doors. >:|
I'm able to reduce the amount errors by fixing stuff before attach another room once I place the door. ...man .. the doors in D3 are some really sloppy work. I made a level just using all the doors to see how fast they are and get a look-see at size and sound. There are a LOT of errors. Once has a double wall and when you turn around after coming through, you're bricked in.
