Oh yes! It was a global announcement so it showed up everywhere. xD
Also that is a good idea. Better than the way I did it this time. D8 I honestly hadn't expected the high demand! Last time it took a few days to get rid of them, holy cow. So next time, when it comes to Connlaoth and eventually Adela, and any future Serenian provinces, that'll be how it's done.
One more Serenian province may be opening up in the next week, so that is something to keep in mind!
