My background layer disappeared. Wtf?
Strange... do you recall how many layers you were working with? This was on your tablet?
About 5 or so layers. On tablet. I noticed just as I tapped save and submit. I don't know if it loaded like that or it blinked out on the tap.
Same general picture. The green underneath just made it duskier. Wish I hadn't drawn on higher layers with the background color
