Something is strange. I tested for Camaret LH (near Brest harbour).
The LH was in the land :
So, I went in Locations.cfg and wrote "OnLand=true". But now, the LH has disappeared !!!! It's strange, because on Helgoland, there is a LH at the top of the cliff, and it's written "OnLand=true" in Locations.cfg ....
I don't understand ....
