How do you get rid of the "Rotten Fish" in Chapter 2 Mission 2?

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.

To get rid of the rotten fish, finish Chapter 2 Mission 1 then continue playing Mission 2 until Eve gives you a quest to build a Weapons/Munitions factory. Finish that quest, then do her next fish net quest, and you will restore your fish.

In my experience, you must do these 2 "side quests" otherwise you will not be able to go to Mission 3, even if you beat mission 2 (by buying the weapons instead of producing them yourself). I think this is a bug.
