Board Game Arena

For the last two games I've settled the Alien Oort Cloud Refinery, I've been unable to change the goods type. You're supposed to be able to change it each action and at game end, but I can't find anywhere in the interface where I can do so. What am I missing? Thanks!

You choose which goods type to place during production and when placing a world. You’re not changing the type of goods, you’re changing the type of the world. You can’t change a good that’s already on the world to something else. For endgame scoring, the type that maximizes your score is automatically chosen
