What if I told you it was just fapello com, i did see on another example, 10 images but only downloaded 9, and it was any of the 10 that didn’t download (it was the 4th image). Link and image source still exists. I can view it on my browser and phone perfectly.

These are just some of them. I would continue on but these are somewhat the links I used to reference the bug.
