See video. 
On quick replace items (such as a belt/underground/splitter), if you place an item over an existing item, the undo feature does no add a ghost of the previous item. I swear that it used to add the ghost of the old item. It would be great if this could be added back as a feature if it isn't already.

The complexities go deep, we want to keep the undo system relatively simple, so unless another developer feels deeply about this, I will move this to won't fix

Thanks for the feedback. It makes sense that the coding is complex, but still thought I would ask since it would be a nice quality of life fix once the player has personal roboports.
