OpenTTD

Fix an OpenTTD client that cannot join because of missing NewGRFs

The server’s running game defines the NewGRF set clients need. Match that set before altering a developed transport network or removing content from its save.

Make the change

  1. Ask the affected player to record the missing or incompatible NewGRF names from the connection screen.
  2. Compare those requirements with the server’s current game and OpenTTD version.
  3. Install matching permitted NewGRF releases through OpenTTD’s content tools or their authors’ distribution channels.
  4. Retry with the same server address and game version.
  5. Before changing the server’s NewGRF set, stop and back up the save and configuration.

Check the result

Removing a NewGRF from an established save can affect vehicles, industries or other game objects. Resolve a client download problem without changing the live game’s content if possible.
