CTD when landing on a runway without a secondary start position

If I create an airfield and remove the secondary start position from the
runway the sim will CTD when I touch down at the threshold of the runway
without the start position. This happens everytime and also occurs on some
default airports. Removing the secondary start position is quite common on
sloped bush strips when it wouldn’t be possible to take off from the bottom of
a runway. It is also common if there is terrain which would prevent a takeoff
from the secondary position. Numerous people have reported the same issue and
I’ve given up trying to deal with this fundamental bug via the Zendesk. If we
can’t remove the secondary start position without getting a CTD on touchdown
why can we remove both the primary and secondary start positions in the SDK?
