I am framing a treehouse and somehow half of the frame is stuck together, as in when I click on them they are all highlighted together and no amount of clicking allows me to select a single piece of wood. They are not locked, grouped, or components. Sketchup just wont let me edit them and i dont know why. The file is attached below. Try to edit a framing member underneath the sign i made (opposite side of the treehouse from the tree) and you will see what i mean.
