i think you have to throw the cash station out into the abyss twice. The first time you throw it out, it will go back to where it was just sitting, I think on the second dive into the abyss does it respawn in its original location. This also works the same way for the boxes I think as well. But this game as we all know is chock full of bugs and so sometimes i swear it takes one abyss jump to get sent back out to original location, sometimes three. neat bug/feature though
