Crimean war

[Crixdaz]

In my last game with the british starts the crimean war and I declare the war to the russians. Then they make a succesful offensive in Kars and the rest of the frontier, the russians lose ~100k and the ottomans ~50k, while i'm attacking their merchants fleets and landing in Sevastopol. All this it's normal but the next turn the russians offer peace to the ottomans and without territorial changes!!! this is normal? the french don't declare the war and I suppose that it's can be a option but the war were very lackluster and seems illogical to me. It's a bug or it's normal?

Thanks in advance

Saw that several times. The AI seems to calculate their own numbers against all of the opposite alliance and a loss of 100k seems to hard to swallow for the AI.
