[0.12.33] Underground belts render incorrectly in bp preview

[JasonC]

In blueprint previews (when creating a blueprint or when hovering over one), underground belts are shifted a half a tile down and to the right.

The offset is visible on the underground tiles in the preview. A more complicated example:



Yields:



To recreate, make a blueprint of any structure with underground belts in it, and the issue will appear on the confirmation preview.

The blueprint does place correctly, it is only the preview rendering that is off.
