Game Progress: Protectorates

I was wondering if anyone had gotten a protecterate yet...

I was starting my 3rd Epirote campaign (first two didn't last long due to economic problems) and I disbanded my navy and elephants, sent a small army under Pyrrhus to the border of Aitolia, while also sending my diplomat to explore Makedonia, and when I stumbled across Demetrias, I asked for a protecterate (offering nothing) and they accepted:

Weird because I had asked for Makedonia to become my protecterate before and they refused...

Anyway, now that I have secured my position as the leader of Makedonia, onwards to Hellas ~D.
