After completing Heliostat to get Wolfsbane, I have run through is multiple times since with both Hunter and Titan. At no point have any crystals been visible to me. I have tried going solo as well as fire team. My buds see the crystals, and tell me where to swing the axe, but I see nothing nor get credit for them. It seems to me like there might be some "hidden" requirement beyond having Wolfsbane. What is wrong? At the same time, while I can easily push items to the vault and retrieve items, the same buds who see the crystals are unable to push / pull vault items.
