Wither Skeletons not spawning in Greenhouses

[mercurialmusic]

Expected behavior

This may be more of a question to make sure I'm doing it correctly than a bug report, but we're trying to allow for wither skeletons to spawn in Greenhouses with no luck.

biomes.yml config section:

  FORTRESS:
    friendlyname: "&cFortress of Solitude"
    biome: nether_wastes
    icon: NETHER_BRICKS
    priority: 18
    lavacoverage: 21
    icecoverage: 0
    watercoverage: 0
    contents:
      NETHERRACK: 10
      NETHER_BRICKS: 10
    conversions:
      NETHERRACK: 25:NETHER_BRICKS:LAVA
      NETHERRACK: 0.005:ANCIENT_DEBRIS:LAVA
    mobs:
      WITHER_SKELETON: 1:NETHER_BRICKS
      BLAZE: 10:NETHER_BRICKS
    moblimit: 7

I would expect based on the rates of ancient debris that spawn that at least some wither skeletons would spawn. We experimented with these rates, even setting them to 100 at one point, and no dice.

Observed/Actual behavior

Even when blocks are correct and space is available, we've had zero. It's the one thing our players complain about the most about these and I'm finally just now getting around to asking.

Steps/models to reproduce

Use biome config above, adjusting rates as desired, build fortress greenhouse, weep at lack of wither skeleton spawns.

Huh. Sorry to hear that. I’ll check into it.

Please try version 1.7.4.

I found a bug where mobs were not spawning at all unless the maxmob config setting was put into the recipe, so actually, no mobs were spawning.

The other issue I found was that wither skeletons have to have 3 blocks of height to spawn because they are tall!

Once I fixed the bug and made my greenhouse taller they spawned:

Thanks so much! Confirming that this fixed it for us!
