Double blocks aren't loaded in structures
The bug
When loading a structure, double-blocks (blocks taking up space of two blocks) aren't loaded. This affects vanilla structures such as igloos and mansions (MC-124390 and MC-124388)
The following blocks are affected:
Doors (all variants, excluding trapdoors)(Fixed in 1.13-pre7)- Beds (all variants)
Tall flowers (all variants, including large fern)(Fixed in 1.13-pre7)
How to reproduce
- Install the data pack mc-123836.zip

- Place a structure block and load the structure bugtest:loadbug

Can Confirm. Doors do not load, but they do save.
This seems to affect all double blocks (doors, tall grass and flowers, large fern and beds). I reworked the ticket accordingly, I hope you're fine with that.
ok, hope this gets fixed in the future
Affects 18w02a
Provided an image with seed and coordinates. The igloo also did not have a Zombie Villager ....
Affects 18w07c
Confirmed for 18w11a
Bug appears to be fixed for Tallgrass and Doors as of 18w20a. Can anyone confirm? Beds load, but immediately break.
Hate to break it to you, but beds require blocks underneath them
No need for sarcasm. The bed breaks even with blocks below, or I wouldn't have mentioned it.
sorry about that, I guess that should explain why beds break when they load from a structure block
In Minecraft 1.13 Pre-Release 5, I experienced beds loading from structure blocks, but immediately breaking, leaving the bed's item on the ground. Voted for this issue.
Edit: I also tried using /setblock to place the bed manually. Setblock could set the foot of the bed, but not the head of the bed, even when modifying the NBT portion of the setblock command. Therefore, I couldn't find any work-around with commands to place the beds that structure blocks failed to place.
Possibly relates to
MC-124955?Just checked, and beds still break when loaded from structure blocks, in Minecraft release 1.13.
However, I did figure out how to use the setblock command as a work-around. I didn't understand how to modify block states in the setblock command, with the new 1.13 syntax, but now I've got it. I updated the Minecraft commands wiki to include the code: https://minecraft.gamepedia.com/Commands/setblock
Here is Cloud Wolf's video that helped me learn this: https://www.youtube.com/watch?time_continue=196&v=R3plRS5eAb4
I've reopened this issue, as it is not resolved for beds.
Still in the 1.14 snapshot 18w48
Can confirm for Minecraft 1.14. Although you can replace a bed with two Impulse Command Blocks set to "Always Active" (so it replaces itself with a bed the second it's placed in the structure) there's no good way to have that be compatible with rotated structures.
To bypass this bug, I wrote a function that would work with rotated structures. The function detects a wool block directly next to the command block that ran the function, and then uses the relative position of that wool block to determine the direction of the bed, and the color of the wool block to determine the color of the bed. I used about 260 lines of code to make sure it had a setblock for the head and foot of each color of bed in each rotation.
