I've found a nice place which was abandoned, placed my totem and started new life. However old settlers left some hearth fires. They are right in the middle of my farm fields. I tried 2 destroy them with demolish button. Tried it about 10 times lost all my stamina, however they seems invincible. So do i just have 2 keep trying or do i have 2 use any tools for it, and how long can i demolish them if they are destruct-able, 10 minutes, hours, days? Or may be i just have 2 wait and they would gone themselves.
Moreover, i cant find a way 2 destroy the results of lay stone action. A lot of stone roads on my lands which i would like 2 plow, but i cant plow those stone roads. How can i remove them?
