Hi,

I am currently flying in Wisconsin and Minnesota. SD seems to have an error in its map data: There is an huge "Dallas class B" airspace everywhere. Once you zoom out, you can see part of a circle belonging to that airspace. Its total size must be as large as the entire US, its center must be located somewhere in the eastern part of the US or even in the Atlantic.

Could you please have a look at that?

I think this was an irregularity in the data we received from the FAA. It was solved over the weekend, anyway. Thanks for reporting it.
