I closed the game to play another, could you post a picure yourself and help me with the solution?
I don't know if it was the same bug, but someone else pointed out an issue which sounds like it was the same issue you're describing. It was a bug affecting potentially 3 of the rooms. I've made a fix now if you're willing to try again. If it was this level pictured below then I have a version ready where you can start from here. Let me know!
Thanks!
