feed updated, but new entries is empty?

[Steven Yue]

Hi, everyone

I'm running updated_feed = Feedzirra::Feed.update(feed) to keep on getting new feeds. 

But there are times when I do updated_feed.updated? returns new time data(which should mean feed updated), but when I do updated_feed.new_entries, it returns an empty array. Does anyone know why?

I'm using feedzirra 0.2.0.rc2

Thanks
