Yes, I too have received bounties from undermining in an Anarchy system. If this actually is a feature and not a bug then it makes it kind useless having an anarchy system, doesn't it? I'm not even sure how to get rid of these now. Interstellar, powers control station? Good thing this is the last week of the last power, that I want there weapon from. If Power Play wasn't a pain in the a** before, now it's just useless. Not sure how to check notoriety, so can't say whether or not I gained any.
New instance:
Was PP hunting in LYR control system (BD+49...) around the nav beacon. I'm pledged to LYR in his control station, I find a ship from Zemina Torval, it's marked 'WANTED|ENEMY'. I attack and destroy, and get a 10Kcr bounty from Zemina Torval! For attacking her wanted enemy ship in my control system!? I hate when games change way to many mechanics at one time. Wasn't this game in Beta for a while? No body playing beta did Power Play?
