I recently tried a flight from VHHH to ZBAA, and I found that the SID & STAR waypoints aren't correct, after selecting any procedure in those two airports (and I assume there should be many more), I observed many long legs on ND, and I can check from MCDU that some waypoints are 6000+nm from the route. I also tried to manually build the procedures, and some waypoints can't be found.
I normally use Navigraph navdata, but I've checked that the same problem exists with Navigraph navdata removed.
