Sorry to bump this thread, but was wondering if it’s related. I have experienced something similar in my game (Just updated today 1-13-2019)
Thinking it may have been underground I started a new world, no specials, no monsters, and it happened in the evac shelter. I get the message ‘hearing footsteps’ and it will make me seemingly go deaf at random and deal minimum pain. This was a brand new start. I went underground and nothing was there.
I debug/killed every monster and it continued. The only consistent thing I have seen so far is that I have my starting NPC there. Even though he was not moving. I realized that in my old game that was upgraded I was walking to the faction camp, where THAT characters starting NPC buddy was when it occurred there as well.
Could it be centered on the NPC’s? Am I the only one seeing (hearing) this?
