Forum:Achievement problems

I'm having issues recieving achievements after completing the requirements for them.

The first problem was with the mission "Shoot them in the head". I got the mission from Crosley, went and collected the keys from everyone by killing them. Then I went to Tempenney and took his counter offer, went back to Crosley and killed him. When I returned to Tempenney to recieve my reward I went through the dialogue and I recieved my reward and it said mission complete. Then I didn't recieve the achivement so I spoke to Tempenney again and went through the same dialogue but without recieving the reward. Then when I looked at my quest screen it said the mission was still active and I had to return to Crosley who was dead.

The second problem was for the nuetral karma level 8 achievement, I leveled up and never recieved the achievement. Not much else to say about that. I gained the final experience points from hacking a computer.

Sorry if this has been brought up somewhere else and thanks for any help.
