I've been playing with the Ubermod for some time and with its 'Gold' version for quite a few time too. In both modes the radar contacts are shown as red and black lines for airplanes and warships respectively. BUT! I think that Uboat Commanders couldn't know if the contact was seaborne or airborne.
In case this is true would you mind telling me how to change this i.e force the game to use only one color for all types of radio contacts?
Is this related to the menu_configuration file?
