Hi Danger Gamer!, I will post the response I posted to you in Reddit: Here are some possibilities regarding what went wrong: 1) Glitch: perform a hard refresh, if that doesn't work clear cookies and cache then log out and log back in. See if the assets return. 2) You deleted the images from your Art Library. If you deleted the images from your Art Library you might think nothing bad has happened for awhile. That is because your browser has a "memory" of things for awhile (this is the cache). But once that memory fades so does the images it was based on. Ie: If you delete an image your game is using from the art library and you still see it in the game it is a computer hallucination. It is not actually in your game anymore. There is no solution to this other than re-upload the image and fix what you deleted. 3) Were you using images from the web via the "From the Web" results in the Art Library? If so: Then perhaps those images broke. Unfortunately the "From the Web" is an ancient (10+yrs old) archived search that is not live. Most of the assets listed in it are dead or dying. Use those assets at your own risk. 4) Something went wrong on Roll20's end. If none of the above possibilities are what happened then you should contact Roll20 via the Help Center and see if they can take a look. Perhaps they can recover the data.
