Hey @VThornheart, very minor bug report/question. It looks like the API reported Grimoire cards don't actually add up to the proper API reported total in all cases. For example on my account, http://www.bungie.net/Platform/Destiny/Vanguard/Grimoire/1/4611686018434964640 the cards add up to 4155, whereas my actual Grimoire reports as 4160. I'd noted that a long time ago when I built out my grimoire page but I just had a user ask about it, and point out that DestinyTracker seems to do the same thing. Example in action: http://www.destinychecklist.net/grim/1/E5%20Dweezil Here's the thread where someone else brought it up too: https://www.reddit.com/r/DestinyTheGame/comments/4gjd6s/easily_track_anyones_coe_completion_for_the_week/d2i26y9 Thanks! PS. The public "/Advisors" endpoint is great, was that only recently added or did I just miss it until now? It's a huge help.
