I have tried to synth the exact same bunch of photos together several times now and I get a different synth % each time. The project is not stitching together properly at all despite 40-60% overlaps on pictures, and then when I go to edit the thing I get a "error saving" message. Are you guys working on something that would cause this?
Chris, I've addressed your different synthy scores on the same set of images on your other topic here:
It isn't a bug.
On the other hand, I can say that I've seen quite a lot of the "Error Saving" message myself, a few nights ago while editing highlights, which isn't normal. In fact I saw the error more than I didn't when clicking 'Save', so I think that definitely warrants some attention.
