App Crashed overnight, erasing 2 hours worth of work - need auto save/backups
I worked on a new files for 2 hours throughout the day yesterday. Just before bed, I locked my iPad and set it down. When I opened the app this morning, there were strange green lines across the canvas. I force quit the app. When I reopened, the illustration had been reset to a far earlier state, losing 90% of the work I did yesterday.
