So to get the price of a double sided coin you have to invade, pick up three motes from the ground the enemies have created, and survive. I did this, but I picked up four (from enemies the other team killed, not from me killing a guardian) instead of three because of a slide, and got out and banked them. The triumph did not proc. Does it have to be EXACTLY 3? Because if it does, that's a little ridiculous that I did more than it required and it didn't proc.
Am i missing something here?
