It has stopped saving keyframes for a seemingly random assortment of properties. The result is that I can work on a scene, finish it, save it, and when I later reload it, a lot of my work is permanently gone. This is also true if I reopen old scenes and save them again.What did Daz do to break the software for you?
In short, the Daz save routines contain a destructive, critical bug right now. I can't work with the application if it will just destroy what I make.
