If you create a new world with the option Generate Structures set to OFF and you try to use the command /locate , it will give you the coordinates of a non-generated structure (it gives you the coordinates of where the structure should be located).
- Create New World.
- More World Options...
- Generate structures: OFF.
- Join the world.
- Type the command /locate and select a structure.
- Click the coordinates the command gives to you.
-> It teleports you to a place with no structure. The game should say, Could not find any structure nearby.
Probably this Works as Intended. Discovered while testing MC-77787.
