Building a spaceship. A green underground belt placed on platform tiles shows both directions depending on which end you mouse over.

How to reproduce:

• Place both ends of an underground belt in free-space. Either free-placement, or copy+paste.
• Rotate one end. No connection will be shown between the ends. (Because the space platform isn't real?)
• Place space platform underneath.
• Mouse over each end in turn, note that the arrows show opposite directions.
• Use the 'Rotate' key to flip one end, note that the arrows flipped at both ends.

Save included, see platform PS1, left side near the foundries.

In the save you've provided the ends are already miss-matched. This can easily be done by placing a blueprint with miss-matched ends, or copying an existing setup with miss-matched ends. When miss-matched rotating one still rotates the other and so they both flip and remain miss-matched. If they're correct: then both remain correct when rotated.

You can either blueprint or copy mismatched ends, or rotate one end while the platform underneath is still ghost. In that case, when the platform builds out, it will connect mismatched.
