Please re-watch the video, the information on that page is correct, please don't change it. The only thing that is dubious right now is whether the plantation +2 major bonus is stackable, so we are leaving it as the tooltip says.
Also, if a future release has something in doubt, please don't leave "presumably" there, just leave it out, we will fill it in when things are clear. Thanks
Yes, you see I thought that Maize was a plantation resource rather than a farm one and hadn't seen the explicit mention of adjacencies in the announcement. My bad (although to be fair, the video doesn't actually state that all other usual adjacencies for the campus are invalid).
