I just made a new kingdom, and I used the Lair of Dark Sorcery or whatever it was called for my throne room. As my new monarch is taking a bath some invisible person comes in and starts a fire in the fireplace. At first I thought it was some cool ghost servant that came with this throne room, but then I realized all the non-heroes were invisible! I could see little chat bubbles above their heads in the other rooms, but that was it. It's impossible to click on them in order to see the interaction options. That's going to make asking them about life in the kingdom a lot harder...
I exited out of the game and I'm hoping that things will be fine when I start it back up, but I still wanted to share this interesting story. Now I kinda wish I would have gotten some screenshots!
Has anyone else experienced this glitch?
