I'm trying to deform a "chain" to follow a NURBS curve, but there's a weird inversion at the bottom of the loop.

I've tried various applies, scales, subdivisions, but the basic issue remains.
Thanks for any insights, I'm stumped.

As suggested in answer to this question that 'stacker' pointed me to below, I did indeed manage to fix this by ensuring the curve and target geometry shared the same origin.
