No, I didn't report it. Don't want to make a mountain of a mole hill. Ramshead is already giving me enough flack for bellyaching about here.
Not sure it is a "bug" anyway. After all, if one has already invested the money to get such and such fortress, do they really want an archaic fortress to show up instead? It is not like the gold is going to be reimbursed.
On the other hand, in my case, I didn't care what fortress showed up, or that I had wasted money, but it would have been nice for the fortress to show up 2 rounds earlier due to the site discovery.
