The first question is why it costs the same as the average to collect small stones in the brink? Is it possible to collect 100 small stones into one large stone in 1500?
I propose to reduce the cost of improving small stones in the middle proportionally, i.e. if the average in the large is worth collecting 1,500, then small in the middle should cost no more than 150.
Small stones will be in demand. At this stage, collecting small to medium costs much more than buying a silverstone at once.

a lot of squirrels...
it is not the average, but the average!!

generally

why is it that all of them are down? then raise the cost of collecting a large stone to 15 pieces

Why is it that everything is just down?

I will try to justify it.
A large stone in a birch costs 40 ecr, i.e. at the maximum rate - 3200 kr. According to the logic of collecting 1500 turnips or 10 ecr, if you increase to 15,000 turnips, the price of the collection becomes 100 ecr, which significantly exceeds the cost of the stone itself, is illogical.

it's long overdue

correct, 1500 turnips is not equal to 10 ecr, considering that the key 5 ecr + 30 minutes of laba = 1500 turnips )
therefore, improvement should cost (if you do not evaluate these 30 minutes in 5 ecr) 3 k turnip )
i.e. small stone ok - can be 1500, and perfect - 3k turnips )

I don't think it's better on the rings. 1 ring = 100 ecr = 30,000 turnips Total turnip is: 1 ecr = 300 turnips, or 40-80 kr = 300 turnips

the turnip is: 1 ecr = 300 turnips, or 40-80 kr = 300 turnips

i.e. 10 ecr = 3000 turnips )) should increase the cost ,

p.c.

why do you compare the real to the virtual currency, which in the game is oversupplied? for turnips, we make 15,000 for real 40 ecr and make it nontransferable
