This is a beautiful map resource that I'd not seen before.

I did a simple model swap for the fixed files, and restarted the editor, but the problem is still present (for me) that the projectiles fly through the gate and the secret wall.
*Is there more to it than just the swap to get it to work? The models are obviously cleaned up/fixed... but I still can toss projectiles through them.

**I mentioned above that when I swapped the gate model for a vanilla iron door model, the projectiles still passed through the gate object.
