Hi
If you make a destruct order, then place a blueprint/ghost of a structure, then cancel the destruction, bot will endlessly try to fill the blueprint.

This was a WIP logic circuit, wanted to do some cleaning but now i don't want to work on this project anymore(planned to make an auto expanding wall with turrets).
Will post the screenshot soon.

The tilling is automatic, you just put the machine and it create the ghost tilling.

Hi !
Here is my WIP automatic tiling machine:


I'm gonna improve it to generate ghost tile only when the system is fed with concrete.
Any tought ?
