I have a page with some grouped items on it, a reasonably simple collection of images and text boxes. When I ungroup the items, they all vanish and I'm left with nothing. This behaviour appears to of started since the latest update to CC (2014.2 / 10.2.0.69). Running on a Mac, 10.10.2.
Pasting the offending group into a new doc and ungrouping works fine.
Any ideas?
