That's worrying. Has it been twisted at all? I would check the furling system to make sure there is nothing which might have caused it to twist.

I also think the forestay is vulnerable when raising/lowering the mast. It is very easy to kink it. I try to keep it as taught/straight as possible when rigging to try to avoid any unseen damage by having someone to hold the furling gear during the operation.

If it were me I certainly wouldn't use it again until the forestay was replaced, the consequences of failure is catastrophic.
