Commitfest app not exporting "moved to another commitfest" to rss

I use rss to follow up on patches that I'm interested in and  it's the 
second time I was wonering where my patch has gone in the commitfest app 
due to $Topic.

Is this a known limitation?
If yes: Is there a way to change this?
If yes: Can/shall I help?
If yes: Where should I start?

Regards,

Brar
