Common Problems

  • I can't start the next part of research, the one that requires 5 completed islands.
  • I have Archipelago Explorer but I'm not able to unlock tier 3 of the war effort upgrade research.

To research your Tier Three War Effort Advancement, the character you're logged in on must have completed Island Expeditions to 5 different islands. This may require you to complete more than 5 island expeditions if you are randomly assigned to the same one twice or more. 

The achievement Archipelago Explorer also requires you to visit 5 different islands. It is an accountwide achievement, but the unlock for Tier 3 is not. This achievement must repeated on each character in order to research Tier Three.
