| Description |
|
Everyone knows that mobs cannot spawn on top of bottom-half slabs. But in this specific case mobs hardly spawn at all below solid opaque blocks with a bottom-half slab on top of it. This somewhat relates to Steps to reproduce:
What I expected: Note that the inner height of spawn chamber needs to be 3 blocks or higher in order to trigger this bug. If it's only 2 blocks high, slabs don't affect the spawn rate as expected. |

Yes I confirmed it's been fixed. |

This may be fixed as it's listed in the 1.0.6 changelog. I tried OPs Chamber-B design (full blocks covered by half-slabs for the roof) and I'm getting spawns inside my enclosed room relatively quickly. I don't have a full size farm though so it would be good to get a second opinion here. |

Related to the fact that half-slabs in Pocket Edition do not block light and it's still present in 1.0.3... |

Confirmed in 1.0.2. Made Mumbo Jumbo's mob spawned design. Spawn rates very low to begin with but add a bottom half slab roof at any height and spawning halts completely. |
