Hej Olof
I’ve already made several reports about the outdated Schengen state list.
2023 entered Croatia the Schengen area
And now in 2024 there will be Bulgaria and Romania joining in March.
I would recommend to export your list into a json file similar to the airport database. Then we can manipulate it by ourself until an official update gets out. 
Will you provide an updated list in your next patch?
