Underground cursor colour
The new shaded 3-d underground cursor has a custom colour. By default, it is orange, which matches the default cursor box of Pak128 and Pak64. However, the cursor box in Pak128.Britain is yellow. To compensate, I suggest that the following lines be added to the Pak128.Britain simuconf.tab file before the next release:
# Colour of the cursor shading.
# Default = 155 (orange).
cursor_overlay_color = 168
