Hello everyone
Not sure if it's known bug, but the attachment nodes on scaled items sometimes are getting misplaced. Simplest way on my 1,2 install to reproduce this is:
1. Place probobobodyne
2. Place modular girder segment on top
3. Make the girder 200% size
4. Clone the girder. The cloned one has attachment nodes misplaced like in the screenshot: http://imgur.com/a/Jc5Tw
This also happens if you clone subassembly which contains scaled part. At first it's positioned properly. But when you deattach and try to reattach, nodes will be in wrong places.
