Autobuild allows your character to automatically build, deconstruct, and upgrade nearby ghosts. A more efficient alternative to mods like Bluebuild.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
I noticed recently, if you die while the construction mode is enabled the overlay is gone on respawn due to it being a new character. the mod should probably check on respawn if the toggle is already active and enable the overlay as necessary.
