Kind of a newbie question, but for whatever reason when I try to rearrange artboards most of the content doesn't move with it.
How do I change the content to be associated with a specific artboard?
Move all the content for a specific artboard onto the same layer.
Oh, layers shouldn't matter, unless they are locked perhaps.
Just ensure the "Move art with artboard" option is clicked when the Artboard Tool is selected.
I did have some things locked, and that was the problem.
