Guild Wars 2

The Informed Politics achievement line cannot be completed currently. All posters can be torn down and contribute to the achievement except for one of the posters in Ascalon Settlement in Gendarran Fields (I’m not sure which one). The dialog menu appears and after clicking through it the poster appears torn, but the achievement does not progress.

EDIT: After running around Ascalon City as a sanity check, I discovered there are actually three posters in that area. One of them was the one I was missing. Perhaps the poster location hints are a bit inaccurate, but there does not appear to be any progression bug

Yeah I have also had the same issue. I have reported it, so hopefully it will be looked into!
