I had this happen as well. I had a radar that was destroyed but continued to show the area for a long time. My guess is that the game thought that they were no longer visible and disabled the movement behavior. But I could still seem them using the remote view.

Looks like this was moved by a moderator to "Ideas & Suggestions". Anyone else impacted by this?

This behavior is leading to other similar bug reports like this: viewtopic.php?f=7&t=117703 (not actually a bug, just that the ghost placement allowed the building's internal buffer to get another fluid).

Any thoughts on if this is intended behavior? IMO, pipe ghosts not checking fluid mixture has been useful as a feature. But I think it is an unintended side-effect that the space platform can never have checks. This causes a frustrating experience, especially for novice players who do not know how t...

Since there is no player, the space platform relies exclusively on ghost building to place structures. However, ghost buildings don't execute fluid mixing checks when pipes are placed. This makes it frustrating to build things like multi-engine ships due to the potential for accidental fluid mixing....
