Demolisher: Confirmed Function
Use Pipe Remover for Pipes. Official v0.5.4 also allowed Demolisher to clear orphaned red blocks when the selection contains no more than 256 tiles; larger scans were avoided for performance.
Setup and Production Role
The tool also protects the puzzle reset button; if that special button is affected, reloading restores it. This recovery behavior is distinct from deleting ordinary factory structures.
Limits and Verification
Refunds, replacement interaction, remapped input, exact selection boundaries, drones and later status of the red-block workaround are unconfirmed. The wiki category says Buildings, but the catalogue classifies it as a Tool.
