ClimbHome: Change misleading Seed assignment to nil value This was "Seed = ClimbHome", but ClimbHome was a nil value. This code still worked as the engine interpreted the nil value as empty string. But it can be very misleading. This changeset makes the Seed assignment more explicit by assigning the empty string directly. The compability has been tested.
