This code is wrong. That must be
Move(Description[1],L.Description[0],Length(Description));
Move(MenuPath[1],L.MenuPath,Length(MenuPath));
Same here.
Move(MenuPath[1],L.MenuPath[0],Length(MenuPath));
Move(TextPath[1],L.TextPath,Length(TextPath));
Same here
Move(TextPath[1],L.TextPath[0],Length(TextPath));
Move(QuestPath[1],L.QuestPath,Length(QuestPath));
Same here.
Move(QuestPath[1],L.QuestPath[0],Length(QuestPath));
These fields are dynamic arrays, in essence pointers to a memory block.
Your code writes to the memory area for pointer, not to the memory area the
pointer points to.
