The Temporal Scoop is safety feature that saves entities from dying in the void at the bottom of a Tardis interior dimension.
This feature requires the Temporal Grace subsystem to be both installed and activated.
When a player entity, or other entity falls to Y level -64 or below, they will be teleported to the nearest available Tardis Interior Door. If there are no doors present, they will be teleported on top of the Tardis Console.
The below preview video demonstrates how the feature works. Note that this is an early preview version of the feature, so some details may be different from the final version you see in-game.
