hm i see why you think the fog removals are in fieldmap, they are not suppose to be showing up there the fieldmap files should end at unrestricted sliab cuilin flight map and the rest of those mods are in the root of \db\ folder structure wise so i'll have to fix that, as far as why the fog removers are causing problems with flight i have no idea as they have nothing to do with flight and each one is most likely affecting each area, so in a sense all of them would be the cause, but i will still have to test in game to find out why.
