| Description |
|
Structure related mobs can not spawn in superflat worlds.
Steps taken to confirm this: Forward Confirmation
Backward Confirmation
In addition, seed-changes were tested, as well as importing confirmed-working chunks into superflat world and manually creating structures through NBTExplorer.
In all these cases structure entities consistently did not spawn while level.dat contained 'flat' - type world generation.

Can confirm, this is still an issue for 1.16 pre-2. I spent a few hours pouring over nbt data trying to figure out why my outpost wasn't working and weeded it out to world type. Also, I tried a superflat preset explicitely telling the game to generate the outposts to find out it didn't work anyway. |

Edit: No longer the case, as moderator merged posts. |

Can confirm that this issue is still present in all versions after the OP's reported versions. For creators trying to make a superflat void world for their Skyblock maps only regular mobs will spawn and Guardian Temples will not even spawn in. |

Still an issue in 1.8.8 and the newest 1.9 snapshot 15w45a. |

Seems similar in many ways to Different details, also much easier to test (just create a superflat world using preset "Water World"). |

Yes, confirmed that it is still a problem for 1.8.1 Prerelease 3 Above directions still apply, use the following for superflat preset: |

Is this still a concern in the current Minecraft version 1.8.1 Prerelease 3 / Launcher version 1.5.3 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. |

Can confirm, still a problem in release 1.7.9. I also was able to confirm that this is directly a result of the world generation settings. I generated a flatland using the settings in the description above, normal mobs spawned (see image generator_flat.png). I then used NBTExplorer and edited the "generatorName" value in level.dat from "flat" to "default". After reloading the world, only witches spawned (see generator_default.png). |

Still a bug in 1.7.2 The strange part is that the "area" in Temple.dat under the data folder is generated and looks to be correct. |

Tested in 1.5 and the bug is still there! |

Removed "CLONE" in the title. |

You've convinced me, confirmed Poking in the code it seems that yes there is a witch spawned by the world generator by default when the hut is initially created, but after that, only the regular mobs would spawn in there. I tried deconstructing the hut and rebuilding the floor at different heights, but nothing would force another witch to spawn there. |

The witch pressent in the pic "Can't reproduce in 1.4.5.jpg" is generated with the hut and not spawned in in the hut. In the screenshot i posted a skeleton has spawned in the hut, and that only happens in flat worlds. So i still claim this to be a bug. |
