I've had Bryce 5.0 for about 6 weeks and so am really new to the program. I've been working on scene with a cottage for about a week. Yesterday I opened the file and found that about 3 or 4 sessions of work was lost. Previously I'd completed the stone walls, a roof, a door and three windows with shutters, but yesterday all I found were the walls and part of the roof. AFter some wailing and gnashing of teeth, I buckled down and redid everything, but I'm wondering what the heck happened. Admittedly, I might not have saved the file after the last time I worked on it, although I don't think so, because Bryce makes it hard, if not impossible, to forget. Since my last work was only doing the shutters on the final window, where did all the rest of it go? Obviously I saved all the previous times, or the door and the other two windows wouldn't have been there when I opened the file to work on the last window. All I find in the manual is the instructions on how to save a file (pg 25). From now on I will use Save As to make another file as a backup, but my big question is, What in the world did I do to lose so much work? Any thoughts?
