There's a grass overhang SGE in the black area.
Acually, that's not an SGE. The blue area is "The Other Side of the World." That means Juni would come out upside-down, so I had put an upside-down'd version of the first screen of TOSotW then the right side up'd version to simulate Juni flipping around to land right-side up. I put that there because that would make Juni able to go everywhere else upside-down, which would disagree with the boundaries of both the level editor and gravity. But, as I'm typing this, I found a better way of fixing this.
EDIT: Fixed all posted glitches/SGE's.
EDIT2: @lamarblake: No, it wasn't. It...broke. I'll fix it.
