I just noticed that, for some reason, the level archive is displaying PNG files from the .knytt.bin blob that contain the substring "Icon.png" (e.g. ArtifactIcon.png) instead of the actual level icon. This happened to the last 3 levels I uploaded (currently at the top of the list). Not sure if this is worth looking into / fixing at this point, but I thought I should mention it just in case.
