In act II, on the human side, while walking around in the mountains you get to a guy with a ring of candles that tell you to get behind the candles when a swarm of monsters attack.

I killed all the monsters and refused to get behind his candle ring. So, the guy goes into an endless loop of calling out to get behind the candles. I went to the other side of the map and the text for him yelling at me is still popping up at the bottom of my screen.

I'm reloading the game to see if it makes his yelling text stop.

Reloaded my save and it's still going on even in the king's tent.

Here is a simulation of what I'm getting on the bottom of my screen every few seconds.

Visionary: Over here! Inside the candles!

Visionary: Quick! You'll be safe here!

Visionary: Over here! Inside the candles!

Visionary: Quick! You'll be safe here!

Visionary: Over here! Inside the candles!

Visionary: Quick! You'll be safe here!

Visionary: Over here! Inside the candles!

Visionary: Quick! You'll be safe here!

...and so on.

I hate to necro a thread, but I can't find anything else about this bug. I just had the same thing.

I happened to come across the guy by accident while wandering around the camp. Since he had a special name, I figured it was best not to talk to him before the time, so as not to cause a bug, but my decision caused a bug anyway.

Talking to a merchant didn't stop it. Meditating did not stop it. Entering a new area did not stop it. Saving, exiting the game, and reloading didn't stop it.

I had to reload a previous save to get rid of the thing.

Did you try to go inside the ring of candles? I imagine the constant yelling must be very annoying, much like the search for Odriiiiiiiiinnn
