ok, fixed again, apparently "Override material IOR" means something different in autodeskspeak - something less "override material IOR" and more "use material IOR anyways", than I would have expected. I hope something else does not blow after the fix ;).

BTW: you are stacking 2 fresnel effects on top of each other, so in the end the reflection you get is very weak. You should set Corona fresnel IOR to 999 when using falloff map. Or even better, not use falloff map in fresnel mode here, since you can get the same effect much faster with corona fresnel IOR
