Windows 64-bit, running 32-bit KSP, with HyperEdit and Kerbal Engineer Redux installed. Also ModuleManager. I'm currently attaching, oh, 30 or more parts at the same time to the craft. What's happening here? Log file: http://www./view/dsy47fzx6ekh3ty/KSP.log (I couldn't attach it to the post, it was too long...) I had just attached a large subassembly on 4x symmetry. Oh, yeah, also: I can't see what symmetry I'm on because it's broken. No idea if I can reproduce this. I don't consider this game-breaking, but it was odd. Perhaps important? I don't know. But I'm letting you guys know. I'll be restarting my KSP now :/. Didn't somebody else find this bug? I remember something about 5-sided symmetry.
