In mission 1 of Chapter 2, the population is getting sick from rotten fish, and I run out of food. How do you resolve this problem?
I’m not sure if you can get the “fresh fish” item from the cove to the north in mission 2. You might have to wait till mission 3.
Setup a trade route to sell rotten fish, and buy good fish. In the meantime keep following the quest line to research antibiotics, after this the issue should be resolved.
