Just like the title says. I got the last jack-specfic chievo (it was suit up) and suit up unlocked but seriously jacked didn’t. In addition, it appears that immortal and grubpocalypse have stopped tracking.
After I got Suit up unlocked, I switched from my Jack campaign to a no-jack campaign. I don’t know if that had anything to do with it. I didn’t run a mission with the supreme gear, I just equiped it. Doesn’t explain why seriously jacked wouldn’t pop.
