[2.0.11] Smart belt dragging places only input underground if obstacle has gap (MR)

when dragging a ghost belt (setting for Pick ghost item if no items are available), the exit underground belt may not be placed, even when the input is.
Conditions to reproduce: have only 0-1 underground belt segments and at least 2 transport belts in your inventory

To replicate, set up 2 parallel belts with exactly 1 tile between them, then drag a belt with perpendicularly across them. Notice that the input ghost underground belt is placed, but the output is not placed with the message of missing underground belt. Strangely, this message appears twice, once over the placed segment and once over the one that is not placed.

This can also lead to multiple input belts with 0 or 1 output belts, depending on how many belts running parallel there are

edit: this also can happen dragging over a ghost, if you first drag over a placed item. I noticed this after dragging a belt across a placed medium power pole which had a ghost underground pipe as the next tile after it.

I would expect exactly one underground input and underground output ghost to be created instead of the current behavior. This always happens when dragging belts over a gap that is either empty or only contains a ghost after a placed item. If there are ghosts, all but the first ghost will be placed over, with there only being an input belt.

A couple more examples with express belts, undergrounds would have been ghosts here but got placed by bots before I could screenshot

Same thing happens still in 2.0.13, running across two tiles of side-by-side north-/south-facing underground hoods, from the west/east side.

Here is a clip from AntiElitz's stream today of this occuring in 2.0.13: https://clips.twitch.tv/HelpfulAstutePe ... 3AgunA3G6f

Also the case for non ghost dragging, 2.0.14.

Interestingly, this seems directional: (all belts were drag-built left-to-right, 2.0.14)

also just observed this, without any gap, dragging over a steel chest, 2 transport belts, and an output underground belt. Haven't done more testing for this at the moment:

Hello.
Slightly different bug report for me but I don't want to be flagged as "duplicate"...

So here it is, dragging from left to right in this situation displaced the perpendicular belt.
2.0.28 with space age only, tested local+multi. Bottom picture is the same with shift pressed while dragging.

EDIT: tested again just to be sure, YES, even with shift, the underground belt gets deconstructed immediately (and added to my inventory)
EDIT2: Tested again in editor, same behaviour. No displacement happens if I have less than two underground belts in inventory.
The bug does not happen if I remove the belts going up before dragging.

Cheers!

This is known but does not belong in this report.
