Presently, it appears the world map isn't editable in most widescreen patched sizes. If there is
serious interest in Custom world maps of larger size then the standard, then we might request for such a fix. Don't get your hopes to high, as it can take several months for them to do it if they have the time and inclination.
Title should have specified 'larger world maps' but I was unsure if it would be transuncted if too long.[This message has been edited by user3 (edited 10-20-2017 @ 10:13 AM).]
