Well, Ghost Town MGC was missing, so I created one:
Ghost Town Money Glitch Canvas

Overview
DOWNLOAD (its also the title at the top there)
As before, I didn't spawn any of the FXs so you'll need to add them yourself (which is less of a pain that running around blind trying to find them).
One spawn point is already placed, but this is just to keep you close by where all the objects are from the start. Its easy to delete as well.
If you're not sure where the power-ups are, they're close behind the stairs.
Let me just explain the reasoning for my placement of objects (since Wii60 owner didn't seem to like it on the b.net forums):
I've put them there so they are out of the way of all "normal" gameplay situations. You can quite happily ignore them while creating your map and even leave them there when its done, since a lot of the time, you aren't going to be up there. But, if they do become a problem, or you need the one extra item, you can easily fly over there and delete them.
Pictures!

Some more objects: (note the power-up seen through the stairs)
The last few objects inside:
A few of the larger objects, as well as teleporters, are just outside:
Just let me know if I'm doing anything wrong, with the posting or the map. :D
