New Warpath Campaign Bug! Any possible way of fixing it?

[Silver]

So I just started the Cherokee campaign and have been playing them for a couple of turns. Early on, the Spanish managed to capture my capital, Autiamique, and I had to retreat to Cherokee Territory.

They had control of the capital for 3 turns, so after 2 turns, Autiamique rebelled and US rebels popped up. The spanish stack moved out of the capital and crushed the US settlers, taking some casualties, and at that time I caught them in the open and destroyed them.

When I marched into Autiamique and retook it, I discovered the Spanish had destroyed all buildings, but surprisingly, the province ceased to generate income.

I built the 3 basic building types in the slots once more and still, the province refuses to generate income. See screenshot:



What must I do? I'm losing 700 gold per turn....
