Mobs not spawning on grass

I was playing in a superflat world, which was all grass on top. On one section of this world, I was laying out some of the new stone blocks (to get a better look at them). Come night, I noticed there weren't any mobs spawning. When I looked at the stone blocks, they were covered in mobs...It's like the mobs weren't spawning on grass at all.

Cannot reproduce, can you please add some more Information?

This is the superflat code I used:

2;7,59x1,3x3,2;1;biome_1,village

Other than that, I can't think of anything that would be significantly different from any other game.

I created a new world with the same superflat code, put down a bunch of different stone blocks, and the exact same thing happened.

Confirmed.

Yes, mobs only spawn in NPC villages

Gary Closse,

Yes, mobs only spawn in NPC villages

??? Create a superflat world with the preset 2;7,2x3,2;1; then you'll have a lot of mobs at night

EDIT: obviously since they do not spawn on grass, so they do on buildings 😃
With the preset "2;7,59x1,3x3,2;1;biome_1,village", mobs do not spawn except in npc villages, right?

I've tested this preset using the new non-ID superflat coding and I can confirm this is still an issue

3;minecraft:bedrock,59*minecraft:stone,3*minecraft:dirt,minecraft:grass;1;biome_1,village

But the real issue is that mobs don't seem to be spawning on Y level 64 as creating the world one block higher does work.

3;minecraft:bedrock,60*minecraft:stone,3*minecraft:dirt,minecraft:grass;1;biome_1,village

Which is reported at MC-55172

Yes, duplicate of MC-55172. Has nothing to do with grass or not.
