Destiny.Components.Profiles.DestinyProfileTransitoryTrackingEntry

This represents a single "thing" being tracked by the player.

This can point to many types of entities, but only a subset of them will actually have a valid hash identifier for whatever it is being pointed to.

It's up to you to interpret what it means when various combinations of these entries have values being tracked.

I don't know, but we can get at it - when I get time to actually test what it is, I'll update this. In the meantime, bask in the mysterious data.
