The extent of my implementation of this involves commenting out some multi z-level specific stuff, and adding a dmi of the overlays it uses.
This currently causes runtime errors due to my lazy implementation!
Only -you- can fix them.

So far as I can tell, it just needs some sanity checks. I would leave this unchecked until the runtimes are fixed.
Additionally, our map doesn't actually fair too badly with proper camera LOS, but there are a couple of areas that need improvement. Please update the map when you tick this!
