Wood harvest (Lumberjacking)
Use hatchets as a tool.
You can chop only one type of log from one single tree. In fact you can`t chop oak logs off a willow tree.
After chopping some lower (up to redwood) tree off, you simply cannot harvest this tree again for some time. If you`ll chop off some higher tree, it will appear in a random place in the world. This system makes “hard-macro” harvesting much less usefull.
Chop some bushes if you want to produce kindling.
