So, I saw Stone patches, they are fine. I do confirm that K2 Disables wood as fuel, but amount of mined turf was suffice. And I also run into softlock of needing Iron to craft manipulator parts for burner inserters - hence being unable to use inserters at all. It's cause is override a main recipie via K2.
Maybe just add alt crafting recipie of inserters via gold or it's products?
