As for "it's too cold"—the cold itself wouldn't be a problem, but the climate is a bit illogical. I start the game in May (in a temperate climate, on default settings)—everything is blooming, there are blueberries, there's no snow or ice. The following year, although the snow begins to melt in March and disappears completely by April, the first blueberries don't ripen until June (so why were they there in early May the first year?), and pieces of ice on the lake persist all summer—some don't melt until the following winter—even though it's scorching hot, and my crops (on the same lake) suffer from excessive heat
