Refreshing the page restarts the whole tutorial, so that is not a workable solution in this case.

The described behavior seems to occur whenever an incorrect action is taken in the tutorial.

In the first step of the tutorial, it prompts you to select the Global Project "Ecological Protection Service" if you instead select "Nuclear Fusion" it (correctly) gives the error "You must play the move indicated by the tutorial". But then, if you do select "Ecological Protection Service" it again (this time incorrectly) gives the error "You must play the move indicated by the tutorial."

Most of the time, the actions you can take are restricted by disabling the confirm button. In the cases where you can instead select a card, that restriction is not present and the error can occur. The next example of the occurrence I found was on the "Play Wind R & D" step. The tutorial requests you to play it on "Clean Electricity Plants", but the interface doesn't disable the confirm button if you decide to play it on another local project, say "Dirty Electricity Phaseout". Playing it on the incorrect local project, you can then confirm the action and you receive the error. After the error occurs and you attempt to take the correct action, it is still flagged as incorrect and you cannot proceed through the tutorial.

I'm not sure if this on the tutorial writer or the tutorial interface, but I'm going to post this here, then share a link with the tutorial writer so they have an opportunity to fix it if needed.

That's correct, and this is happening with any tutorial. The author of the tutorial can't do anything about it. It's part of the BGA code base.
