   Still not sure what the root cause of this is, but here's what we've found so far in the course of debugging:
   
   - The steps listed above are not actually required to reproduce the issue. All that is required is viewing a chart in explore. It would seem that loading the explore page somehow writes the chart to the db.
   - The chart list view is using the `changed_on` database field, which gets set to `now` automatically any time the `Slice` model is written in the db.
   - Loading the chart in Explore a  _second_ time does not trigger the same update to the `Slice`. This issue might only apply to example charts, if they have some special condition that organically-created charts do not. Needs further testing.
