Given key not present in dictionary

I downloaded a korean route and loaded it up. The loading got to the 50% mark and then an error message popped up saying "A critical error occurred when parsing the route file." The BVE crashed

I tried to open it up in routeviewer to find the errors but I got this instead



Link to the route:

Thanks, fixed.

Was caused by the secondary rail for a platform being there, but not the primary one.

I've also made a change, which will speed up loading of a lot of insane length routes including this one.

(TLDR: If the .Turn command is used, this requires a bunch of additional processing, which we can skip a lot of the time)
