I tried. Didn't fix it.
I'm having the same issue on my side. I noticed inactive red beast being spawn in the node before. Red beast being spawned elsewhere might be the problem because when I arrive on the Echoing lair node, I have no red beast to kill, only a yellow beast.
I'm having the same problem, it just spawns a yellow beast and when I kill it nothing happens
