Linked FB avatar not refreshing

Hopefully this will be an easy question... I have my profile here linked to my Facebook and I'm using my FB avatar as my avatar here. When I change my profile picture on FB, it doesn't seem to sync up or refresh here. To get my new FB profile pic to show as my avatar here, I have to disconnect the accounts, then re-link. Anyone else have this issue? Or can anyone else tell me if there's a setting or a way to manually sync the two?

I would imagine the issue is with ball-pythons.net so not much you can do but that work around you have discovered. I would suggest ball-pythons.net using a cron job every hour or so to refresh the connected accounts facebook picture.
