This week on the Portal we have Accelerator: Special Surge - Increase Special weapon damage and ammo drops, however on the Challenge Modifiers, Special Ammo Famine is locked which means I cannot select. Now, I cannot achieve GR 8 because it is a requirement to complete an activity with a Famine modifier active. I am locked for another week on my GR. Is this intended Bungie? What is the alternative here?
