I encountered a problem with the quest - "Tree is Man's Friend."
I found the central, half-destroyed tree, and I've tried everything there, danced around it, rotated the camera, stood still, waited for a week (7 days, not turns), and even ran to the dryad (my wife even started getting jealous), but nothing happens; the tree remains unchanged. After this quest, is there a chain of events, or can I just forget about it?
