I stumbled across the Dhustone Quarry BEFORE "The Supply Line" mission. I freed the prisoners and cleared all treasure out. And in the process destroyed a supply cart. When the mission popped and it started it showed I had a quarter bar already done for destroying supply carts. So I figured get the rest and call it a day. Not so fast. Get there,destroy remaining 3, still says I'm missing something. Walked around entire quarry, tried reloading ,nothing works. Help! Playing on PS5.
