Yeah, they're losing against Prussia/Poland until I decided to help them. I gave two provinces I conquered to my British allies but they just built improvements and didn't build any troops so the Prussians and Poles reconquered those provinces. They did this again so the third time I conquered those provinces, I just gave them to the Austrians. That should keep the Austrians from breaking our alliance again.

The reason I'm giving those provinces away is that I don't want to be bothered with fighting the Prussians and Poles.
