This is a very low-priority issue, but the fix is straightforward.

The "Parameterized Adventure" demo exploration has an error, as shown in the screenshot below. It would be nice to have a clean copy of the exploration in the codebase.

The fix involves loading this exploration locally, fixing the exploration to remove the error, downloading the generated YAML file from the history tab, and replacing the yaml file in the codebase with the newly-generated one.
