Bug report:
The "Having a Purpose" quest is still showing up twice in the Active Quest menu;
The "Navi" menu is unavailable after checking Kor's Etheria Tank with less than 30 pure etheria. To make the Navi menu available again we have to click on Kor then either select "Transform & Build" or "Back".
... also, how do we harvest pure etheria again? I do (sorta) recall it naturally appearing in the ponds (or was it the forests and meadows again?), but not really sure when they show up.
