Yet another potential bug in SW2016. I was working on an assy of about 35-40 parts, nothing too big or complex. Just simple sheet metal parts. I tried to move a hole in one part of the assy as i have done millions of times in the past. When i clicked on the check-mark the whole assy disappeared. Nothing i could do to make it reappear. I had to do a save all, close down SW, and then reopen it......WTF is going on with SW?

Note to the development team at Dassault, Forget the new shiny features that make the software look worthwhile to potential new users, and make the simple everyday tasks that engineers need to use function......WOW.....
