One of the facts I got for california was 'It's lone star represents Texas' which is wrong but I think it's just a glitch
Comically, this clue is intended to refer to California, as it was another independent state at the time of the mexican-american war and is believed in folklore to have included a lone star in the top corner of bear flag designs early on, as a tribute to its brother Texas! (Though the more I read about this the more tenuous it seems, and folks might have just really liked stars in those days)
