I did a search and could not find any info about this so if it's a common or answered problem, please redirect me.
I seem to have this issue where the entire map is covered in the "radiation" effect, when there is in fact no radiation. New maps don't start with it, it seems to develop with my builtup areas and around 20 squares away from them.
Software is Original w/ Rush Hour, all the updates and STEX Vol 1-3
I've attached the DXDiag below.
