Ah, the joys of roller-furling!
This often happens when people fit furling gear and find out that either the forestay, laden with the furler foil, is too heavy or a newly-recut forestay is too short that they can't connect it to its proper point, so they attempt to cut corners-- which, as you have discovered, essentially amounts to redesigning the rig. And this is what happens.
(Actually I'm amazed it got to that degree. Did it go suddenly? I wonder if the stress fault had not been evident beforehand.)
Since my boat had been whacked into a piling by the PO, I removed my stemhead fitting and re-'glassed and faired the whole deck area. It's not a hard job to do, providing you can get the forestay completely off the boat and still support the rig whilst you work on it.
