When Keyontae was still in a coma, I changed my avatar to a picture of him. For a few minutes, it was working, but later switched to a blue box with a question mark. I figured maybe it was copyrighted, so I changed it to a disc golf basket. Same thing happened. OK, maybe that was illegal too? So I changed it to a solid orange square. Same damn thing happened. How do I successfully get my changed avatar to "stick?"
The same problem, but after just a week, everything went away by itself. Maybe this is a periodic bug.
