Two minor bugs
1) The option More Concession to Prussia never unlock, so you can't activate it
2) when you activate the options Alliance with Savoy, all the Savoyard cities and forts but Turin remain in bourbons's hands, the Bourbons' Savoyard army still remain in game, and Victor Amedus is duplicated: one for the Grand Alliance, one for the Bourbons (you will find the Bourbons' Savoyard army in Vercelli, and the Grand Alliance's Savoyard army in Bergamo)
