I've been shooting pirates at a compromised nav beacon and it's a lot of fun. There seems to be just the right mix of difficulty there without it being too difficult. If I feel like bit of a challenge I can take on a wing rather than singles. However, some weeks the nav beacon reverts to a regular nav beacon which means there are rarely any pirates there. So my question is then, how does a nav beacon become compromised? Is it possible for a player / group of players to assist with getting it compromised? or is it something that just happens? When it does change it seems to be during the weekly BGS update on the Thursday so it would seem to me to be affected by the BGS in some way.
