Oh and BTW.
Did you change the navigation map? V3 Showed a more precise underwater topography.
Might be a bug on my end IDK but the map is very minimalistic. Wich can cause an issue with planning routes. I usually travel over zones where I can dive deep but now I got nothing on the map to help me find those.
I'm all in for immersion but some concessions has to be made for a game to be enjoyable.
If the change was intended, could you make the old map as an optional addon?
