I had one left in Oceania with :08 to go. Got Nauru with :01 second on the clock. Fun quiz! Of course, if I hadn't got that last one I wouldn't have thought it was quite as fun. lol.
Pretty sure Tuvalu is also missing. I always look for the 4 island grouping of Tuvalu (noon) Samoa (3) Tonga (6) and Fiji (9) and only see three of group.
