I also have this exact same problem with the Opals not clearing from the map if you die soon after picking them up.

I also have the same problem.

I am still unable to loot the Hamptunscire hoard map. It is suppose to be in the dirt beside the tree but nothing for me. Also the Oxenefordscire and Eurvicscire maps are still bugged. I have completed both of these but the maps are still in my inventory.

This is after the new update has been installed. I am playing on PS5.
