Phantom prospect assignment kill doesn't count

After spending two days, trying to come up with a solution to this problem, I think I found a remedy for some people. If your having this problem, try  redownloading Premium and see if that works. If it doesn't, another soultion might be to reinstall the game and all the DLCs. That was the customer supports solution to me, but it didn't work, although he said it has worked for a lot of other people. 

Sorry if it doesnt work guys, but I felt the need to post this. I know how frustrating it is to have this happen, and I have yet to see a solution to this problem, so I wanted to share it with you guys. Hope this helps!
