In my COOP-Game I play with my wife we sometimes encounter diving spots at which we can't dive. This happens since 9.0.
Those are always the random diving spots, not those you get from treasure maps.
In my recent singleplayer game I've started, I am also encountering this problem, now one time I actually encountered it during the quest from nate where he shows you where you can dive for some pearls to restore the scepter.
The button for diving (the one which takes 10 seconds) is simply greyed out and can't be clicked.
