I have posted a message on Skyrim_Jacob's Bethesda site for the Forests of Skyrim mod to let him know that his mod places trees that interfear with the cabin. Specificly a large tree right where the front door is located. Some other trees are spawned that take up a lot of the area your mod is using as well. I turned off Forests of Skyrim till Skyrim_Jacob can fix or i grow out of the Hunter's Cabin of Riverwood.
