I have had a couple of times in the last week where I built a number of features. I complete the last feature and when I close that feature SolidWorks starts undoing the last 6-8 features I have created. It runs backward like an animation. When it is finished the 6-8 features that I created are now gone forever and I have to recreate them.
Has anybody seen this behaviour? What is this?
