Ah, yes... I remember that being one of the slightly more obscure inputs. Getting the spade doesn't seem to do anything at the moment.
I've been digging the sand until it looks like a quarry. No joy, I'm afraid. Maybe that's as far as I can go. I guess I'll have to put it on hold until the final submission.
Yeah, I think we will need to go back to the tower to retrieve the location as to where to dig. But that bit isn't in there yet.
