I'd like to report a bug. When I copied my horizontal stabilizers to make a single vertical stabilizer, it made a duplicate over it. Each time I remove the duplicate part and then save the craft I get the following: https://www.dropbox.com/s/lclrup8455lsq8e/2014-08-21_00001.jpg My controlls are entirely stuck and there is no way to get out except for stopping the Kerbal Space Program process. When I restart Kerbal Space Program and I load the craft, it's just like it was before with the duplicate parts over eachother. Keeping the clipped parts isn't a solution either because either I got something like the screenshot beneath, or exploding parts. https://www.dropbox.com/s/xhiyha4qy7xj6gb/2014-08-21_00002.jpg
