I've completed the story so I'm just going through and doing any remaining tasks.
Mainly my concern is with the loot chests. Although I can see them all on the map now I've bought all the additional treasure maps there are a few I cannot get (locked away in Citra's temple for example).
If I want to get 100% completion on the game (meaning the in game judged 100%, not Xbox / PSN achievements) can I just ignore the loot chests? Is there anything else not covered by the Progress handbook section I need to take into account?
