I had forgotten about that. I have the rules downloaded, and I remember reading it at the time. I vaguely recall putting it in the too hard basket though. I think it was a combo of my mod needing a lot of rework, and me being unclear of a few rules about the scenario. It's been ages (three years...wow) but I feel like I posted some questions to the BGG forum and never got a response. I'll dig it up and see If I can give you a clearer answer. Have you managed to play it in some other form?
