I just used Amethyst... Now it's broken more though?

So, Amethyst did upload this image, but I have to manually type in .webp at the end. Is this an Amethyst issue or an issue with your server leaving the extension off?
Its undefined behaviour, the extension is optional, and i think the client should add the extension, snort does it
