Just saw it does this on the export... whoops! I'll be honest, I don't know what caused that since it works fine in the debug console, so definitely something funky in either how we uploaded or otherwise something it didn't like for a more convoluted reason. But, we published 3 minutes before submissions closed so it is what it is. No way we could have finished in time and spotted the error lol. There's 2 more level sets before the end, so we'll upload a polished version elsewhere a later time for any interested in seeing what more there was!
