Not a bug, but an enhacement idea: for beginners, it could be a lot of help to list all needed components not just Special game parts.
Example: world 513, you play with residents, so you need some player-number-dependent residents (2p: 30, 3p: 25, 4p: 20, 5stock: 15).
Also, AFAIK all game with residents needs all settlements (game 513 surely needs them and they are not listed).
