Check that you're not in peaceful mode. Also, make sure mobs aren't spawning nearby underground. This is why I recommend building at Y-level 200.

Assuming your game mode isn't set to peaceful (derp), if it's not working then it could be due to an update that changes how lighting goes through half slabs. If so, try replacing them with full blocks and see if that works.

@W0nd3r: Ignore my previous comment. I just read this: https://minecraft.gamepedia.com/1.13/Flattening - we're going to have to wait for MCE 2.0 to support 1.13 saves.

The download is a schematic, not a map, so it should work regardless of what version of MC you have.

I'm currently using this as an FTB base playing solo. It really lends itself nicely to the various mods. Not underwater but half in a cold biome, so it has a lot of the glass covered by snow.
