also invisible silkscreen rect should not appear in gerber (or should appear in sketch)

Broken link. Should be http://fritzing.org/forum/thread/1424/ .

I think I am experiencing this bug. I have two instances of a part, rotated CW and CCW. One of the instances generates an improper solder mask layer for Gerber (some SMD pads are not masked, so that the copper would not be exposed, rendering the board useless unless you scrape off the mask.)

I am trying to think why this is not higher priority. My best guess is that this is a rare bug, some peculiar combination of data, or of copying and rotating, or of using a custom part. I can provide my sketch that reproduces, but I hope to experiment and find a workaround or a simple way to reproduce.

I could not reproduce the problem starting with a new design, adding a part, and rotating the part. Fritzing 9.2b using Sparkfun Discrete part nmos transistor in SOT323 package.

However, there is a workaround: delete the errant part and recreate it. In other words, it might be a data corruption problem. Or some obscure sequence of part manipulation.
