Sometimes dragging belts a specific way causes extra belts (see video link). I have been able to reproduce the issue with ghost-placing belts in the editor, building real belts in the editor, and ghost-placing belts in-game. I can't reproduce the issue 100% of the time and I'm not sure exactly what technique / circumstances cause it.

To reproduce (inconsistent):
- ghost-place a belt in a straight line from point A to point B
- Keep dragging & holding shift, but move the cursor back towards point A
- press R
- move the cursor in a direction perpendicular to the belt

It may help to interchange the order of steps 3 and 4.

You can see in the video my various attempts.

P.S. I saw the new experimental release notes today and all the bug fixes you have all been working on. I'm impressed by the dedication and attention to detail.

Ref.: 129705

was able to recreate it in curent experimental 2.0.47
both on windows and mac specific versions

Can you reproduce this in 2.0.49? I tried it a few dozen times and it's just not happening.

I'm able to reproduce this consistently on 2.0.55 by pressing R *before* dragging to the side, while the cursor is still on the straight belt. Pressing R after dragging to the side does not exhibit the bug.

I reproduced this today while playing Space Exploration with game version 2.0.76.


Steps to reproduce:
- start with the 2 tiles of ghost belts shown
- have upward belt in cursor
- while holding shift, click and drag to the right
- press R while dragging to extend the line of belts to the right
- keep dragging, and drag to the left
- press R
- drag one tile above the row of belts
- release shift
