On almost all maps, at least on my front end, there is 'brown land' where water used to be. for example (not sure the map, but the high 5.0K base with in the middle of the terrain with a lake to the West (some have called it squid lake?), looks completely filled in and is FLAT brown instead of water blue. The catch is, it still acts like water... if you ditch in it you sink a little.
Other areas of the maps show blue water; however, its not accurate to where the 'water' actually starts.
I have tested this out in different areas of the maps... This happened to me today. Driving an M3 to town, I was traveling on Green ground, then as I got closer to the coast, I got into the brown ground... then I could see the water off in the distance; however, maybe halfway from when it turned brown to where the visible blue water started, I fell into the ground as if I were falling off a ledge into the water... (even though there was no color change on the map), and relative to the game I was sitting in the water, even though it still looks like land.
I have spoken to other people in game and they have reported this as well.
Any thoughts? Something wrong with my maps? Do I need to re-download them?
