The model was not uploaded then. I figured out what was causing the bug and went around it to upload my scene, so the bug is still there and it doesn’t let you upload your scene.
The bug is seemingly caused by adding a diffuse map as a color on your material, its perfectly fine most of the time, but suddenly you add one more and this bug appears. On one instance removing that material and replacing it with a fresh lambert fixed it, on another case I had to remove every single material that had a diffuse map and replace them with just basic grey lamberts for the bug to go away.
The most frustrating part is that if you google this bug you find a couple of threads like mine, but none of them ever get solved, nor do the people respond and say that it was fixed.
