EDIT: Relates to MC-60193
Again, I found this in a 1.8 snapshot, though I don't know if this is fixed, so I'll still report it. So, I was in a Stronghold searching for an Ender Portal, and I found a half/cutted door.
What I expected to happen was...:
A full/normal door would generate.
What actually happened was...:
A half/cutted door generated.
Steps to Reproduce:
1. Find a Stronghold (you can do that with Ender Eyes)
2. Search for a half/cutted door (they are not easy to find)
3. If you found it, then enjoy the half/cutted door.

What's the seed of the world?

@Jasper van den Berg
Actually, the "lighting glitch" was because I had played the Beta 1.9 pre-release 3 as far as I remember before playing the 1.8 snapshot, so the game automatically setted "Smooth Lightning" to "Disactivated". Altrough it shouldn't happen.

@Jasper van den Berg
I don't even remember. Minecraft Seeds are one of the easiest things to forget.

@Jasper van den Berg
Ok, I got to the world with the bug in Minecraft 1.8 and the seed is 3268861822896236472.
Coordinates are 724 44 243.

Confirmed for 1.8.

Cannot confirm. At said seed/coordinates is a stronghold, but not a door

I don't remember the actual coordinates.

Just fly a bit around and you will find it.
x: around 690, y:14, z: I don't remember that one

690 / 14 / 309

@Kumasasa
Thanks for reminding me the coordinates.

Apparently, the door vanishes after clicking the button that triggers it. But I don't think that compensates the bug.


@Jasper van den Berg
Actually no, the problem is due to strongholds overwriting only non-air blocks, and I have read that in the wiki.

Found out something. The bug has been confirmed about a week or two ago, but it's still in unconfirmed state.


Able to confirm in 15w31a.

Is this still an issue in the most recent versions (i.e. 1.10.2, or 16w42a) of Minecraft?

Unfortunately (or maybe fortunately) I cannot verify this issue in either 1.10.2 or 16w42a, because the stronghold doesn't at the same place on earlier versions for whatever reason.
