Kerbal Space program 1.0 part duplication error when using [ALT] + Click to duplicate part. Steam updated stock version. New Career game after update. No Mods. Tried to use Alt click to duplicate the Elevon 1, but after clicking the part did not appear and all other parts became un-clickable. I used [Ctrl]+Z to undo placement and then duplicated part appeared placed where I originally wanted it, but does not have any hover-over action and does not respond to undo and redo commands as shown. Error has spread to other parts. Any part that I try to edit now becomes unusable. Parts now stuck to mouse. Pressing Delete will not get rid of part. Cannot exit SPH with part stuck to mouse, had to force quit game. Seems a restart of the game has fixed the error. At the moment I cannot reproduce.
