There is a/an (secret) achievement on Saints Row called Pimp Killer. You get it when you kill the pimp 50 times in the Protect The Pimp online mode. Just today, I got my 50th Pimp Kill. Yet, I never got the achievement. This pissed me off so much because I tried pretty hard to get that achievement. I never got a notification saying "Achievement Unlocked" or whatever. I even got another pimp kill after that, yet still, nothing. This has nothing to do with PTP, but it's a similar problem I had before with SR online. There was another achievement called Bulletproof- where you complete the co op mission in the airport level at the Kingpin difficulty. When I completed it the first time, I didn't get the achievement, and I was like, wtf. Then, the second time around, I finally got the achievement.
Please, I need to know this. Has anyone that has Saints Row experienced these problems? If so, please, try to help me out and tell me what I should do. I really need to know if it's my fault, or if it's SR's fault.
P.S.: I have done the pipe bomb glitch in PTP multiple times. Do you think I didn't get the achievement because of that?
