Idk if these forums are reserved for more serious bugs, but I'll report this nonetheless.. Basically, the game won't stop making custom markers on the map, and it's kind of annoying. I know I didn't make them because I've had the game saying I had a custom marker so and so meters away when I had just started the game and had never even opened the map before, so I couldn't have possibly made it, even by mistake.
It happens in every save. I remove them but the game generates more custom markers, not always in the same place, but they still keep appearing. This is happening on pc.
