It works now! The the custom props showing up and physical in the map.
I didn't know there were stairs and such in some of these areas. Makes a lot more sense now!
There are a few areas that seemed to be see-through though. (That weren't before in the previous version.)
Here is one, near Red's second spawn/second point:
As well as inside Red's second spawn:
And this one area past Blue's Second Point (in that little area to the right of the boxes: )
I might not have caught them all. And it may be possible the problem is with my client or server running the map incorrectly, or just some random error.
Not a map-breaking bug, just not sure why I'm looking through the floor.
