Twisten fails to update from all sites

Twisten is not collecting my tweets from other music services (posting from twisten and collecting from grooveshark posts works fine). I post from last.fm (http://bit.ly/19R8IP) and the hype machine (http://bit.ly/wDnkC) too and neither of those are coming through to my twisten playlist (http://bit.ly/xTAhP). This is a real shame because I love the service so far - if only it worked for all my music sites.
