Save System Corrected

Hello! Sorry about the error message that would pop up at the start!

I had unthinkingly added the save game script for SugarCube instead of Harlowe, very silly of me, but hey, it's a knee jerk reaction.

So now it will actually save your progress! (And not pop up a little error box, let's just forget about that, shhh...)

God be with you all!
