Able to hear calls in homecaves

You can hear other dinos distant calls, like broadcasts while inside homecaves, while I dont not have proof of this to upload right now, I was a spino in the underwater homecave in northern cedrus and my friend was in the land hc in northern cedrus as an amarg and we could hear eachother broadcasting

Able to hear broadcasts of other dinos in other hcs while you are in a hc

You shouldnt hear other dinos distant calls in hcs
