◆ FixOwnerOfRailTrack()

void FixOwnerOfRailTrack ( Tile t )

Tries to change owner of this rail tile to a valid owner.

In very old versions it could happen that a rail track had an invalid owner. When conversion isn't possible, track is removed.

◆ InitializeWindowsAndCaches()

void InitializeWindowsAndCaches ( )

static

Initialization of the windows and several kinds of caches.

This is not done directly in AfterLoadGame because these functions require that all saveload conversions have been done. As people tend to add savegame conversion stuff after the initialization of the windows and caches quite some bugs had been made. Moving this out of there is both cleaner and less bug-prone.
