As a part of a new NG update, it looks like everyone's art from after January (?) of this year has apparently vanished, but DON'T PANIC! The image files still exist, they're just not displaying! I also heard that Tom and the other NG staff are currently working to fix the issues! In the meantime however! Newgrounds user @raviolibox figured out a fix! I'm just here to share the info!

All you need to do is this! Go under your profile drop-down list and click on the "Your Projects" tab, and they'll all still be listed there! Just go and "edit" each one and click "Publish Changes" for every missing upload, and they'll display right back in their original order on your page (and everywhere else on NG) again! It can be tedious, but if you don't want to wait for the staff to fix the display issues, it's at least a good option to have!

Here's the video Ravi shared showing exactly how to do it too!
