[2.0.72] Underground ghost not being placed on lava

[crimsonarmy]

Note: foundation must be unlocked for this to occur. (It occurs when it isn't unlocked too but then it isn't a bug)

Attempted to force build dragging a ghost of a belt over lava with a building right after the lava. (It occurs to me as I am writing this that I only tested this with pipes and green belts; I don't see why it would matter but thought I should note it)

A ghost of a normal belt appeared instead of an underground.

I expected an underground to be automatically placed so the belt remained connected (like the oil ocean in the attached video).

It happens consistently

Steps to reproduce:
1. Place a pipe right after lava
2. Force build a ghost belt by dragging from the side with the lava over the pipe (It just occurred to me I never tried going the other way)

Edit: added note at the top

This is not what my bug report was about. Note that foundation is used but an underground is not made.

I see.

I am considering this to be a duplicate of 116827 since belt drag building depends on undergrounds finding the other end and currently they are unable to find other end through tile ghosts.

Purely for my own curiosity, why does the oil ocean version work?

Because underground connections are only blocked by lava tiles and empty space tiles. Oil ocean does not block underground connections.

Makes sense. Thanks for humoring my curiosity.
