When dragging a belt over a ghost, if one comes upon an underground belt, the smart belt dragging utility automatically places the undeground belts. If the player has no underground belts in their inventory, then a belt is placed where the starting underground ghost was, deleting it, but does not delete the ending underground belt.

The image outlines what happens when dragging the belt from left-to-right. When dragging from right-to-left, the rightmost underground belt ghost is deleted instead.
Edit: The expected behaviour is for the belt adjacent to the chest to not be placed, and for the ghost underground to remain.

This is not only about placing over ghosts.
More relevantly, this also happens if pulling over an empty space.

That issue is not tracked in this report.

I would argue @sben's comment relates directly to this issue. When placing items, I expect behaviour not to depend on the exact contents of my inventory. If ghosts must be placed instead, then ghosts should be placed instead of the unexpected behaviour of my screenshot and @sben's screencapture.

This relates to the older issue (99227) that items are removed from the player's cursor when the inventory is depleted instead of automatically switching to a ghost cursor. As a QoL feature, the user should be able to place items in the game without regard for whether they:

• are in map view or regular view,
• have a ghost or real entity in the cursor,
• have enough of the entity in their inventory for the current build, and
• have their personal roboport active or not

Depending on which of the above cases apply, building behaviour can be interrupted by the cursor being abruptly cleared instead of gracefully switching between ghost and real items as appropriate.
