Recently I was trying to reply to a comment and it wouldn't post the reply. Today I also wanted to upload a meme but the image wouldn't upload, so I resorted to using catbox.moe. Even with that, it still insisted on generating its own broken image and the thumbnail didn't generate either
UPDATE: Apparently only GIFs and replies are broken. Uploading a JPG or PNG works fine
