I was working on three icons last night for two different LIMS. I was spending a lot of time on them. I had done many many stages of background creation, coloring, textures, etc. I Photoshopped for about an hour before I got too tired to work and decided to go to bed. I just left Photoshop open, and it didn't occur to me to save the PSDs.
I didn't have time to get on the computer this morning.
Came home from work, made dinner, reading flist, la dee da, I will finish those icons. Wait. Photoshop isn't open.
COMPUTER INSTALLED UPDATES ON ITS OWN AND RESTARTED. ALL LOST.
