I updated my MongoDB to the new engine (Wired Tiger) and made no other changes.
Now when I run my app and run ‘meteor mongo’ in a separate terminal, there is no value in a collection (db.collection.findOne() returns null) that does show a value when I log it to the console from a subscribed template.
I think my app may be using 2 databases? How can I check that my app is only using 1 mongodb?
