Why do comments seem to be removed from images?
I have come across the same bug images with illegible labels multiple times, and when I take the image to discuss, I find previous comments and suggestions have been removed. This makes it hard to label consistently. Sometimes I can retrieve the image with comments from my Profile list, but that is very time-consuming.
If in doubt, leave it blank. There are so many to do it won't matter and each record is transcribed three times for accuracy checking
