The Bug:

Villagers aren't loaded and beds are permanently occupied when loading structures that contain villagers sleeping in beds.

Saving a structure containing a villager sleeping in a bed (using a structure block with "Include Entities" on) and loading it in another location causes the said bed to be permanently occupied and the said villager to not be loaded.

Steps to Reproduce:

1. Download the provided structure block .nbt file that contains a bed with a villager sleeping in it. mc-264048.nbt
2. Create a world and place the .nbt file into the generated\minecraft\structures folder.
3. Place down a structure block with the appropriate data already inputted into it by using the command provided below.

   /setblock ~1 ~ ~1 minecraft:structure_block{ignoreEntities:0b,mode:"LOAD",name:"minecraft:mc-264048",posX:1,posY:0,posZ:1,powered:0b,showboundingbox:1b,sizeX:7,sizeY:4,sizeZ:7}

4. Open the structure block and click the "LOAD" button to load the structure.
5. Attempt to locate the villager that should have been loaded.
6. Attempt to sleep in the bed that the villager is supposed to be sleeping in.
7. Take note as to whether or not villagers aren't loaded and beds are permanently occupied when loading structures that contain villagers sleeping in beds.

Observed Behavior:

Villagers aren't loaded and beds are permanently occupied.

Expected Behavior:

Villagers would be loaded and beds wouldn't be permanently occupied.
