I think a good majority of developers have been experiencing some issues pertaining to textures in the past week. I have had to request to appeal 42 image assets in the past few days alone. To say the least this has been a very unproductive, frustrating, and stressful past couple of days for me in regards to roblox game development.
I’m having the same problem too!
I fixed this by using the original image link. Not the one that comes from the game. It is very frustrating though to convert all of this because my game heavily uses image decals.
Does the Roblox staff have an estimate on when this will be fixed? This bug makes it so hard to develop since no images are showing when running the test server.
