The sniper rifle in Sapienza was particularly difficult to unlock and now it isn’t in my inventory anymore. No doubt a far more difficult method to unlock is in the works.
Items are missing from people’s inventories because of a bug. (And, at least for me, they are still in the actual inventory, they just don’t show up when you try to smuggle them in.)
IO is in no way removing them intentionally to re-add as future unlocks.
I use digital. The first time I even looked for it was the other day. It might have never been there. I wanted to equip it for a contract and it wasn’t there.
So probably only certain Xbox users locked out of Dartmoor. If I miss an elusive target over this I will be very upset. Of course for all we know there could be an elusive in near future requiring a combat axe kill under penalty of insta-fail.
