Visible bubbles when a survivor is hooked is gone (sometimes), sound is deadened
When a survivor hooked on the other side of the map, the echo'ing reverb of them being far away isn't happening. It sounds like they're in a padded room with you. The visual bubble indicator around their body is no longer showing in some cases.
On the Yamaoka Estate map, when Feng and Keith were hooked, it didn't show.
On the Fractured Cowshed map, when Nancy and Claud were hooked, it showed.
On both maps, the sound was messed up.
