It's updating for my main image in my profile view, but not for the sidebar on posts or in the mini-view: I assume it's some caching issue? If so, no worries, I am a patient man. I will check back in a few hours and post here that it is solved. However, if it's some horrible underlying fault in the system, I hope that my post has averted some unmentionable crisis.
OK, so I thought it might be some weird cache thing: nope.

deleting my current avatar

deleting the new avatar
posting a link to the new avatar
uploading the new avatar
again, deleting the new avatar
