I am experiencing a bug in minimongo when trying to sort a collection. The bug only happens in part of the collection was subscribed (on the template level) on a master template view and then you navigate to another view that displays the entire (filtered) collection. I.e. notifications of a new activity vs viewing the entire list of activities
Activity.find({}, { $sort : { createdAt : -1 }});
Its kinda of odd that this is happening but for now I was able to fix it using underscorejs to sort
_(Activity.find({}).fetch()).sortBy(function (num) { return num.createdAt; });
