All of the following was done in the vanilla versions offered by the launcher.

Executing the command "locate Village" in a world with generated structures disabled makes the whole world freeze, yet you can still interact with it, and after a very very long quit to menu and save screen, nothing gets saved after the command execution.

Works with any world, any gamemode, as long as structures are disabled, the argument is Village (or something else depending on the world) and cheats are enabled.

The command probably loops forever and doesn't allow some of the game's functions to run.
