Me and some friends hold a yearly charity stream where one of the games we play is OpenTTD. We've been using the CityMania event NewGRF with the NoCarGoal script, but the latest version of the CityMania event (1.5.1) works very differently - it has big gifts on the map to which you can deliver goods and passengers and no industries (to begin with). I found an event page on this website (https://citymania.org/events/9-christmas-event-2023) and tried to load the save game there, which had rewards and victory points when you delivered goods to the gifts. Is it possible to get this functionality to work in a normal OpenTTD game using the CityMania event NewGRF and if so how?

Thank you!
