Care to explain what happened in the bug? I haven't encountered the issue with it so more information would be appreciated.

Ok ok, that's not a bug, Bel warns you that there's a certain angle that is correct. Even if the image is "correct" it has to be in the right angle. Just a hint, head on the upper left and butt on the upper right. Also on the second puzzle there are already correct pieces meaning you don't have to touch some of them.
