I know how to make thumbnails in scratch but this day it was all white. I saved it while the thumbnail sprite was shown as a normal guy would do but it just wouldn't load the thumbnail it is just pure white also for my other games It was annoying since I was going to share them and no one would click on a blank thumbnail so please help me fix if you know anything that could work or please try to contact scratch for this problem thanks.
