Reachable hexes display in night snow scenarios does not function

[qbert55]

The reachable hexes display does not function in night scenarios with snow (e.g., "Midnight Madness" in EF). Does anyone know of a tweak I might try to address this? Thanks.

Works for me. [&:]
 
I checked it through both 2-D and 3-D modes. It is harder to see because the white of the snow and the grey of the night. But, it can be seen on my computer monitor.
 
Could it be the brightness level of your monitor is shading out the variance?

The 2 D works a tad better, especially if I turn off background lighting. Thanks.
