Missing activities

I've noticed in the past 48 hours that not all of the activity for the people I'm following is showing up in my update feeds. For example, Xanadon't posted comments to his April Journal list, but it didn't show up in my feed (and looking at his update feed shows me his last activity was 4 days ago, despite the comments being made on 4/30). Or maybe his activities just aren't being updated for some reason, but I only see updates for maybe 5 or 6 of the 24 people I follow.

The updater stopped for some reason, should all be up to date now.

Thanks Tom!
