I wasn't able to find this answer by searching, and I apologize if this is a duplicate.
I have, from time to time, found ways to reproduce an access violation against a given save-game. (v1.0x)
It would probably be best to email the save game, and a short description of how to reproduce to Stardock, but I don't know what the preferred destination/format/information for such an email would be.
Are there instructions for such things out there?
