Experimental Gameplay

Enabling it on an already existing world adds an "Experimental" tag right next to the game mode name in the world menu. Once the experimental world is created, it cannot be turned off again.

Warnings

Attempting to disable experimental gameplay toggle via external tools could also crash and break the world.
