I've been away from my PC's for the last 2 weeks or so and have noticed that no snapshots have been sent for around 18 days (except for the one PC with version 0.8) . However, when I look at the computers that I'm currently using the list is saying that a snapshot has been sent in the last hour but all the stats are reading zero. Like this one for instance.
