There are a lot in the workshop. However, I don't know if this track was done yet - and please note that the currently available tracks don't have the visual quality of the official Hong Kong track (at least not yet).
I agree!
But if you had this unofficial clue to break the branch ....
There are some clues that seem official, but besides being few, I think it's very expensive for being one track only
I found this one in Santiago in Rfactor 1
