Help: "Necessary Roughness" quest in Kezan is bug

Greetings,

Today I started playing with a Goblin, but in starting zone there is a quest that is not working, which is "Necessary Roughness" given by Coach Crosscheck in Kezan.

When I start the quest, I have to drive a robot called Bilgewater bucaneer, after that it is supposed to show Shark robots, but they are not visible. It informed that the quest is failed multiple times, even without starting it.

New players like me would like to know if this bug can be fixed or not.

I hope that this quest zone could be Fixed, because when I played in Gilneas, I generally worked well.

Thank you!!
