Randomly going deaf?

Hi everyone, so recently my characters have been going deaf while just walking down the road- there’s no indication of what caused it, I just get the “your ears start ringing!” message. There’s nothing nearby to explain it, so I’m guessing it’s a bug. Any help? Hopefully my character hasn’t been deafened for too long.

There’s probably an explosion or weapon firing nearby, quite often below ground…

It’s possible that there’s something underground going on… any loud noise nearby will cause going deaf.
Collapsed towers and/or burning buildings nearby might also be an explanation…
