Couldn't find your account because you didn't mention your in-game name. Found it now though.
I can see the error in the logs and I have set your score to what it should be. Will investigate this issue. Seems to be related to getting score multiple times from one action (robbery + achievement + achievement bonus). In the next version the achievement bonus score will be combined with the base score to perhaps reduce this happening.
I will add some detailed logging to the score system so if this happens again I can check why.
