Can I reinstall?

[Sinkmore]

FWIW, the worst I've seen was a week or two of extreme bad weather. I could barely see 200m by day, and more like 40m by night. I was almost ready to give up and return to base when the sun finally came out.

FWIW, I -think- the game (depending on the mods) randomly considers changing the weather every x hours? So I think it's possible you've just been unlucky. But if I were you I'd be considering restarting the mission!

In any case, I don't think you'll have to reinstall the game.

Is there a chaplain aboard? You might try that first.

Or, are you playing in 5000 BCE? If so, you must gather your family, and build a ship, 40 cubits by 200 cubits. Ignore the neighbors. Then you must collect all the animals, two by two, and put them on the ship, with fodder for ~40 days at sea. Maintain radio silence. Be on the lookout for seabirds.
