After some experimentation, I've found that I hardly get more than 1 sapling from a tree, sometimes even none at all. If a player is to be able to farm the wood sustainably, they need to have an easier time obtaining sapling.

I'll think about it. But in the future, another mechanism will be made for the extraction of seedlings, in addition to what is already available.
Several days a year you can collect seeds and germinate them.
Thanks for the suggestion.

Ah, I did not know there was a time of year that was beneficial to such activities. Do you have plans to write a guide to explain all these hidden features?

No, at the moment the season does not play any role. This mechanism is still in development ...
At the expense of the guide were plans, as soon as time will appear.

Yes you are right. The chance is very small. I should increase it.
