So i made a small tree farm, with spruce saplings, planter works mine.. plants and does what it has to, but harvester is doing absolutely nothing, i mean it's not stuck on idle, it doesn't have sludge inside it, but it just won't harvest that big 2x2 spruce tree.

Harvesters do harvest spruce trees, make sure the tree is in range, and the harvester is facing the right way.
