I know that I've run into that sort of thing with heightfields with a reflective
finish.  That was some sort of "known" bug, that I have no idea ever got
investigated or fixed.

Perhaps you can try to reduce the reflectivity of the surface - Only the very
upper/outermost surface should need a reflective value.

You can also try to render _just_ those blocks with the appropriate command line
switches, so you don't have to wait 48 before testing that region of the render.
