Once I close the lid on my properly packed cable box, I think the cables have a meeting to discuss who will go where - because when I open it back up, they are all rearranged.
I got this problem too...I actually have 4 wire bags 3 active and one for extra spares at home. One goes with each set of gear that is still in use and one holds any combination of wires and the video cables and the lycra screen and a bunch of other stuff I'll likely never use but need to prevent me from having an anxiety attack LOL
