How do I do quest "The Other Stone" ? I went into the cave before I got the quest, and killed the boss guy for the shard. I then went back but I don't know what to do.
The corners that do so you explode if you go off the track really sucks. I have to slow down by a lot everytime, while the computer players just rush past me.
