So I put 5 hours into a Sketchup Free model last night, and saved my model multiple times while drawing, but today, the model in my Recent Files has the model as it looked when I started the model, putting about 20 minutes of work into it, not the final version, after the subsequent 4:40 hours of work.
I would assume that there was some system maintenance last night, but is the updated file gone, or can it be recovered? I don’t see a recovery option in the free version.
