Yeah - to add my own experience with this;
Bought the game and started playing 4 days ago. The first thing I did was take the "liberate 2 slaves" mission from where I started (LHS 3447) and as a new player, I had no idea how to do it.
A few days of learning, mining credits etc. and I finally had managed to get one of the missions from federation that earns you a rank. On that exact trip to get combat stabilizers for the federation and upon heading back I bumped into slaves being sold by accident. I had one "liberate 2 slaves" mission from where I was mining aswell, so I bought 4 to complete both slavemissions.
"Perfect", I thought - as I could just go back to Frey through LHS 3447 and get that mission done. I hadn't even noticed there was another completion option for it in the description and decided I will not go after the credits and do the "right thing" and get even further good rep - as I've been wanting to play as a good guy - at least for the time being
Get to LHS 3447 and the mission just isn't there. Nothing at the bulleting board about it, where I should return it - yet the description clearly lists that station as the return point and ERAVATE as the optional delivery point for the enemy of the federation.
I did visit Eravate just to see if I could return them there - and I COULD but the reward listing in the bulletin board menu was 530 credits. Not the 53000 credits that the description says...
And like I said, I didn't feel like being the bad guy, so I ignored it.
A bit later I went for another spin at LHS 3447 to check if I could return them there after I had got a few newer missions out of the way, but nope - couldn't be done.
And when I abandoned the mission, I now got the same exact text as you can see in the screenshot of the original post;
"
"GETTING GOOD WITH THE LAW
I can't believe this is the life you've chosen for yourself, Commander. Don't you want to be something more than just another common thief? People are already starting to talk about you, and not in a good way. Petty thug, pathetic crook... is that really what you want people to know you for?
There is another option. The cops over on $##abaDestinationStationName;
STARPORT CLEVE HUB
SYSTEM ERAVATE""
And whatever reputation I had worked for, is now gone - apparently unless I do the mission... a mission, that I have no idea what it's about :S
Edit: And I emphasize; I did NOT return the slaves to the opposition - I abandoned the whole task and got that text in there, as if I HAD turned them in to the enemy of the federation.
Edit2: I did NOT accept any "branches" or take on any other option for said mission from any other bulleting board. The "Liberate 2 slaves" contract got updated with the whole "I have spies in LHS 3447 that tell me blah blah, deliver their resources to me and I'll pay so we'll laugh at them, blablabla"
So... I really fail to understand why so many people here are trying to spin this off as OP's fault or mistake, when it's VERY clear that the whole mission scenario is bugged - in more ways than one. And "You should avoid missions like this" isn't a reason to tolerate bugs. I took the mission to do good, for no reward but reputation. It's not in any way my fault as I got "into illegal behavior" or did a "shady mission", when infact I didn't. It was all for a good cause and described as such.
