I think this is a bug with the Spruce Tree. I see pines on the tree so it seems ready to harvest. The tree is 100% in the dome and I already harvestet twice from this tree before. The hover text says : "to pick up = 0" so there should not be anything to pick up. When I try to pick up it says "inventory full" even though I have plenty of room in my inventory.
