Having got everything working and GWX installed I start a mission. So... there's me, gently paddling round when I come across a cargo ship in the middle of the night. The thing's lit up like a christmas tree! Searchlights here and there and, particularly, searchlights on the black flag it's flying.
Black flag? Out of curiosity I manoeuvred closer but no, even from under 1km away it was still black. Ho hum.
Is this just me being an idiot or is it a known bug? Is there a workaround?
