I also had a play after reading your comment and I had such a similar experience haha. Haven’t seen the issue with the placement state in hero phase yet but certainly got tripped up by forgetting to replace a key or the hero using a key in the wrong order. At round 30+ you get the best ending message but the hero got stuck on 33 so I didn’t see it lol. Thanks so much for playing probably even longer than me, I think you’ve well and truly beaten the game now!
