Thanks for the feedback!
The idea behind the goal is to try to make people to get as far as possible, but at the same time try to hide their caches so they don't get stolen by other players (as they can't be close to them to "protect" them because they need to maximize their score). The problem of the game being incomplete is that some things don't really make sense right now :(
Sorry about the bug! Indeed, I can see that player "Yirggzmb" last position was (1162, -1035). You explored a lot :)
