I really can't recall seeing this problem before, but I now seem to have bizarre white / pink ground tiles at night surrounding all terminal buildings:
I'm assuming that this must be something that I've 'introduced', but for the life of me I can't think what...
Btw - FS9 installation.
Any help or suggestions much appreciated.
GaryEDIT - Just found out that it was some thing that I'd 'introduced'...
