Count Geonor voice lines continue and overlaps after I kill him

I killed him right as he was backing up into the fog where he would enter the phase where he starts saying lines and jumps through the fog at you. But when I killed him right when he was about to do that he continued to do the voice lines as the hooded one came and talked so the voice lines were overlapping

Can confirm. I encountered this too.

Same here. Here's a clip: https://www.youtube.com/watch?v=X9v30h9mfUg

Just got the never stopping voice lines bug too, killed him as he was calling the fog just as the other users
