The box that has the info about me on my profile displays my avatar, but it seems to be showing one of the other avatars I saved a while back. Does it simply need time to update or is there something wrong with it?

Try hard refreshing (Ctrl + F5) on your profile page. If that doesn't work, clear out your browser's cache and that should do it.

Yep, it's just a caching thing. Just hitting f5 will make it update :)

Awesome, it worked! :D

Thanks guys!
