Disappearing node, and crash

[GaretDH]

A simple circuit board model, using rectangle pattern for end contacts. If you have a look at Sketch 3, the pattern on the left has somehow lost its reference node. It's just gone!




And, of course, if I try to move that pattern GM simply crashes.

The problems with using sketch patterns is that they lose associativity after closing the sketch - so going back and editing is tricky. I almost always use feature pattern because it is so much more robust.

I was able to get somewhere by double clicking on one of the shapes, this opened up the dialogue and pre-populated with the correct spacing etc, but it put the reference node at the other end of the pattern. I was then able to move the pattern, but the separation dimension between the two sets of contacts didn't make sense.
