I tried to generate custom flat world in my server.(just small and for testing)
So i wrote generator setting format like below


When i entered server, grass block didn't generate.
So i opened and checked again but there wasn't any problem(in my opinion)
I guessed that there's problem in world and opened level.dat with NBT Explorer.

In level.dat, grass block layer changed to air layer.
So i tested generating world a lot.(without grass layer, adding one layer, etc.)

Then i could know about some problem about generating layers.
When layers are more then 5, fifth and upper layers are change to minecraft:air.

I think this is one of bug in paper.
I want fix this bug.
