Italian campaign. High difficulty.
Piedmont-Sardinia becomes France's protectorate after losing Turin. It is a part of scenario, script. So, it shouldn't be a problem for player. But later, when Piedmont-Sardinia restores its army and France's army is far way, Piedmont-Sardinia declares a war to player. Considering a scenario's terms and a limited time, it looks like a bug.
Is there any way to solve this?
