Yeah?! I bet you probably saw one of my posts in a Facebook Group. Really, I'm trying all my options because hopefully INNRevival will eventually return... But there's things that can't be fixed without having additional content. I was already able to fix The Arena thanks to finding FOOTBALL on an INN Install with Torin's Passage, and the aforementioned expansion packs should unlock 'The Little Red Funhouse' in the bottom right of the map.
