Food, provisions etc will come with Privateer's work on import/export of the GR2 models I'm sure. I did previously manage to get a bunch of bananas into a new room with Goblin but something went hideously wrong in game. As soon as I walked into the room with the new bananas I was teleported off the boat to external view! Not sure what happened.
At this moment I'm trying to add new waypoints for the new crew. We'll see what happens
