Deer full scene corrupt (Patreon)

Here is the corrupt files :/How is the chronology?

I have completed the full scene bases in the morning. However, the file is still open in the painting application (I use paint tool sai V1.0). I m sure the file has been saved. Then a few minutes later, the electricity down and my pc shutdown. Because I felt sure I had saved it, I didn't worry about it. Then I away from pc, rested until the evening because I had a fever and planned to continue the full scene sample at night. When i open the file this happened :/

I have asked my friends as if recovering, because SAI does not have auto save and save history, finally I gave up. I will repeat making it from the beginning.

Incidentally I once posted a screenshot of my work screen after the file was ready. This is clearly visible and I can trace it again. Do you want a new scene or keep tracing the old file?
