Repro is trivial. Part design, new body, new sketch, rectangle, pad, 2mm, select side face, extend -> error.

I've tried it with 0.19 freecad and with realthunder branch -- result was the same.

Reverting commit fef6bb2d310c8f8acc62b242ec8bad54385139e4 fixes the issue.

Related to #238

Just note that correct spelling would be subtraction

Is this still an issue ?

I haven't checked it with newer versions of the plugin. Let's close it as it should be fixed as per @shaise
