I might be being a bit thick, but I had a custom avatar once, and one day it disappeared from my posts. I figured it was some kind of glitch, so I deleted it in my profile by checking the "do not use an avatar" box, with the intention of uploading it again afterwards. However, the custom avatar/upload option simply disappeared. Has this happened to anyone else? It is, admittedly, not of enormous importance, but I would quite like my pig back...
