One of the types of achievement is collecting coins. I've had a ton of money, guessing that's not the kind of coin they mean?Is that a late game resource of some kind?

but why!!?

Цена этой игры в русском регионе - 1300 руб. Для примера, Baldur's Gate 3 - 1999 руб. Никто не купит эту простую игру по такой цене. The price of this game in the Russian region is 1300 ₽. For example, Baldur's Gate 3 - 1999 ₽. No one will buy this simple game at that price....

it's weird not to have one.

I get the animation of sticks, leaves, etc. when I break a bush, but the amount in my bag doesn't change at all. Rocks and trees drop resources fine.
