Recently, mapper announced that they would delete their Geoguessr account and all associated maps including A Diverse World, in protest of the direction that GeoGuessr has taken recently. In this same post, mapper also mentioned GeoHub as an alternative to GeoGuessr. I don't know if they've been in contact with you directly, but if not, this is something you may want to be aware of.
