When right clicking on any sector of the map the game willl give you the status of any base in that sector...
INCLUDING ENEMY CARRIER GROUPS.
Normally, An enemy CV is invisible, but it seems that the code supporting this feature doesn't inhibit viewing an enemy CV>
All A player needs to do is right click every sectory one at a time and sooner or later he is going to detect an enemy CV.... I'm sure this is not intentional and is a bug. Please fix.
