Z-levels are bugged

[Robertha89]

Here is a map i made this round
#5# #3# #1# #7# #6# #4

313 131 444 656 565 777
#4# #3# #7# #1# #6# #5

I believe this can be solved by actually adding 3 empty z-levels. Cause a z-level going to itself???

Err, not certain how this map works. Do note that Z levels use a torus, as explained in #2193. The PR linked inside of #2193 should have a map that shows what the torus should look like.

The map seems to work out fine. It just doesn't make a ton of sense from a topological standpoint because all our Z-levels are the same size and our space people only move in two dimensions, which makes the shape sort of non-donut-like. (Because most people think of single-hole things when they hear the word torus.) If it were a single-holed torus, heading North then East would be the same as East then North.

I'm sure it's technically a multi-holed torus by topological standards but I just think of it as interconnected space loops.

Yeah, the topology is really weird, but I'm pretty sure the behavior describe is what's intended. It is indeed multiple toruses connected in an arguably non-euclidean manner.
