In this saved game, John formed the major company FS and merged minor company #10 into it while one of the minor company's reserved hexes, U6, was still unbuilt. Result: Rails will not permit FS to lay track there.
I'm not sure whether reserved hexes are supposed to remain reserved after the minor company that owns them closes -- but if they are, the successor company should certainly inherit the right, rather than the hex becoming unbuildable by anybody which is what has happened here.
