That sucks that you can't save any of the decorative bricks. I made a Slender map and the trees didn't load. NONE! It took forever to make the trees too. (The map was HUGE) D: But other than that, this is a very good add-on meant for everybody to use. And I say that everyone should use this.
I've seen the video before. And I'm still scarred to this day. Sucks too, Rainbow Dash is my favorite pony. .____. But yeah. Good job for posting it. :)
