[its a viic]

I know this is going to sound like a silly question to some of ya but how do you change your patrol grid? I see where it is slightly grey but I am unable to change it. I have gone in before a patrol and cant seem to get it to change. I currently have the old 2.6 version not the newer one. Also what happens when you rollback commander? Does it go to your previous save settings?
Its a pain going to these far off grids when I just want to troll for convoys in my viic!!



Other question..... when I want to change to the new commander what steps should I follow. Thanks.
