Except once you're doing a mission it will automatically track it again once you hit the point where the marker was, and then updates to the next spot. Constantly, because it may just be the next room over. No matter how much you switch away it will come back. Such a gigantic bummer. Who do we need to reach out to to do something about this instead of shouting into a void on various forums?
It has reached the point where I want to put down the game until I can play through some quests without this dumb thing on screen screaming "GO HERE" all the time. Beyond the super annoying and immersion breaking eyesore it is, I cannot stand this type of forced guidance at all.
If we have to wait for official mod tools which might be months and months away.. holy shit.
