I created a mission just to test my skills if you like to try and get through the English Channel, when I went to the map I noticed another sub icon, there isn't another sub there but the icon is following the player sub.
Also right out of the blue the free camera is now sticking with the player sub, I've never had this option before and I don't have any patches installed, I'm playing with the out of the box sim.
I can still click from ship to ship on the free cam by the way but the player sub is in the cylce of views.
Any ideas?
