Simply thx for that one. I had Schalls pickup towers installed, but even with the additional type MK4 it always was a brutal job to remove all artifacts after I cleaned an area I planned to use for building production on it, because the artifacts would end on the belts otherwise and block them. On top, the type 4 tower tended to get corrupted on loading a game and was split into a radar and a chest. And placing 30-50 of the towers also was a tedious job.
