I'm almost able to progress to GR8 but I need to do an activity with a famine bane. When I try to activate Special Ammo famine it says it's unavailable, I'm pretty sure it's because this week has a special ammo surge but I could be wrong. It's pretty frustrating as the surges normally last a week so I won't be able to progress until next reset. I'm sure they will be plenty of others who may also be trying to progress this week.
