[2.0.39] Forced underground belt ghost not placed

[sben]

What did you do? What happened?

1. Copy an underground belt entry part with a pipe in front of it.
2. Super forced build this over a belt line
2.1 before placement, underground belt exit part is shown to be built
3. underground belt exit part ghost did not get placed

What did you expect to happen instead? It might be obvious to you, but do it anyway!

- Super forced build preview differs from the placed ghosts.
- Missing exit of underground belt.

Does it happen always, once, or sometimes?
Always
