Same problem here.
Uploaded new squadron noseart ( apdrone.bmp ) last week and the only person with new noseart is me. Of course, this doesn't indicate the upload actually worked, it just means the software is pulling the bmp in off my machine anyway. BUT, since I didn't get any error messages, I figured the upload went ok.
Figured.. maybe it gets propagated through the servers on the weekend.. no..
Maybe when scores reset?... um..no...
Is there a magic 'refresh noseart now' button somebody might have covered up by an empty twinky wrapper?
