So I got bored and decided to make a new scenario based on the Cold War: The Fifties scenario. Basically lifting all El Justo's work and plugging it into an even larger map. But I've run into an issue. The scenario's allowing sea trade whereas the original TCW: Fifties scenario blocked it. I changed nothing other than adding a few more units, so I can't figure out why it's doing this. Does anyone have any suggestions what's up and/or how to stop it. I've checked through all the improvements and wonders and none of them have acquired the "Allow water trade" flag.
