I recently upgraded to Matlab 2016a, and I've been trying to edit a .fig that we previously made. When I save the figure and reopen it, I get a nearly blank figure that looks nothing like what I just saved. I've tried making all kinds of figures from scratch and that always works fine. Many of my old figures can be saved and reopened too, but not all of them. Since many of my figures have a lot of data that takes a long time to calculate, this is really annoying. Any idea what's causing it?
