Bug #7925 caused this behaviour:

  • Loading the savegame involved calling Load_RAIL, which filled _railtype_list.
  • Loading was aborted before AfterLoadLabelMaps, so _railtype_list was not cleared.
  • The titlegame is old and does not contain a RAIL chunk, and thus LOAD_RAIL was not called.
  • Thus the titlegame's AfterLoadLabelMaps used the _railtype_list from the aborted savegame.

Funnily noone bothered to add the equivalent of AfterLoadLabelMaps for road types, so an alternative fix may be to just delete it.

…ng a savegame instead of at the end.

Otherwise temporary data may be passed from an aborted load action to the next load action.
