I don't know if this is the proper place to tell the bugs but I just got one of the old cursor-spinning problem. In the change from 1620-21 I got the secret order created warning and just then keeps spinning, the old workaround of waiting for a time and then alt tab to game didn't work. I think it could be related to that event since I think it is focused in austrian faction not in spanish one (the one I am playing).
By the way I love the mod but just I could say regarding to this new faction, I don't see very historical to set the capital at that city in Burgundy, much more accurate would be one city of the spanish netherlands as Brussels that was court of the Archiduk (and in the game is just a fort...), Antwerpen as commercial node or Brügge as other prime importance city. Dont take this as bad criticism.
Grettings and thanks for the hard effort producing the best historical TW mod at the moment (with permission of EB1).
