PHDays Hashrunner challenge 2015 - Writeup
I had a similar issue. If you downloaded the Window pre-compiled binary then you are unlikely to be using the latest bleeding jumbo. Try this command below and check the results:

john --list=format-tests --format=scrypt

If the result from the last line looks similar to the output below then it is not the latest bleeding jumbo.

scrypt  10    SCRYPT:16384:8:1:VHRuaXZOZ05INWJs:JjrOzA8pdPhLvLh8sY64fLLaAjFUwY
