Actually, it was just a structure I'd built that had...millions...okay a few hundred struts on it for stability and strength(only way it would make it into orbit), and rather than remove all of them manually, the weld tool actually made the job easier, as it would ignore them in the import process. It's not a huge deal, as now I'm building parts with this weld tool in mind, so I don't include the struts anymore. It was just a time saver for some older stuff I'd made. Anyhow, I appreciate your work continuing the development of this mod, makes the game playable!! I was making a station that was made up of about 10 or so other modules, of nearly 1000+ parts each. Kerbal with 10K parts on screen is a slideshow.
