Trying to paste the top row onto a straight line of belts going the same direction. Preview suggests that another underground belt is added (middle row), but after execution it isn't (bottom row). I don't think that the extra underground belt is a good thing (see 129883), but the preview doesn't even match what is going to happen. So I thought it warrants a separate bug report.
[2.0.60] super-force-paste preview incorrect

I cannot reproduce this on internal 2.0.61.
