Forgive you?
*whacks IndyPendant over the head with a clue-by-four*
Now, kindly tell me what in the name of everything holy and unholy made you think you needed to apologize beforehand when posting THAT? As if we haven't been looking for the cause of that particular bug since Dominions 2 and nobody has ever had ANY idea what caused it and it's nearly given several people here apoplexy. This one is about as close to the Holy Grail of Dominions 3 bugs as is possible and such a detailed description is going to help narrow it down greatly.
*runs off to update the shortlist*
