Thank you for playing, rigg!
You should be able to put the cables back into the docks by hovering over any of them, but there is also a “secret technique” that I hint at in the contract - If you stretch them very far, they will snap back into the docks! The ones that fall onto the desk were supposed to break (and later respawn), but I think I forgot to add the visuals for that.
Sorry for the confusion, but thanks again for playing!
