I just finished up my third Heroic Strike for my Warlock's milestone and for the Solstice Gloves, and picked up the engram from Zavala. At Zavala's vendor screen I noticed that I only had 60 tokens, where only earlier today I had roughly 770. Where the heck have my tokens gone and how do I get them back? I'm pretty livid about this, I've been saving up tokens for a while now and all that progress is just gone.
