Good! The changes were realism-based, but this is what I was hoping for!
Have you seen New England forest winters? You’ve got snow, and bark, and twigs, and that’s about it. Weeds? Tubers? How will you find them under a foot of snow, buried in ground that’s frozen too hard to dig through? There’s a good reason most animals prefer to fatten up or store a larder, then sleep through the whole season. Which reminds me - most of them shouldn’t even spawn in the winter, except perhaps deer, rabbits and turkeys.
Winters should still be pretty survivable, even without looting towns - if you’re prepared for it. Food just no longer leaps down your throat by itself, is all.
As for acorns: blackjack oak acorns aren’t really edible without extensive treatment to remove their tannins, and even if they were, they’re only ripe in the fall, same as acorns of the white oak, which ARE edible. So rather than make tanbark only available in the fall, I added acorns as an autumn forageable instead.
Pine nuts: New England pine cones have nuts, but their nuts aren’t what you’re thinking of when you think of pine nuts. Those nuts come from an assortment of desert pinyon species out west. These nuts are generally a waste of effort to extract. Even such an inefficient recipe as we have is being a bit generous, imo. They’re not what you’d consider a major dietary staple, and if you’re reduced to eating them to get by, you have officially fallen on hard times.
