Hourglass'd gennaker

Well I had an exciting event this afternoon, probably by my earlier gloating about successfully hoisting the gennaker. After a beautiful downwind run I needed to furl the gennaker for a few hours while I close reached northward before taking a turn to the west. The first part of the furling went fine but there was quite a bit of tension on the furling line for the last half of the furling process.
When I tried to deploy it again after making the westward turn it hourglasses on me. I didn't take pictures as I was too exasperated/exhausted with trying to resolve it. Here's what an hourglasses gennaker looks like:
