Bug: flipping pasted contours

I’m finding that when I paste contours from one letter to another and then try to flip it left to right with the flip button, the contours smash down to one vertical line occasionally. If I undo, then click to deselect the pasted contours, then select all, the flip button works fine. The flip up and down button is fine too.

I can’t reproduce it. Will have a eye on it.

Ah, I figured out when this happens. It’s when I also have a guideline selected that the flip button turns up this bug. The pasting isn’t necessary. In other words:

  1. Select a guideline as well as a contour.
  2. Press L/R flip button on Transformations palette.
    Can you reproduce that?

Can you post a screenshot before and after?
