This is causing issues with me streaming heroes of the storm. It breaks the audio for the rest of the entire match if Anub’arak cocoons someone with his level 10.
Once the cocoon ends, the audio effect from the cocoon is not removed. It stays for the entire match regardless of which hero is being selected. It’s not a rare bug, its basically always happens if Anub’arak is a Hero with that Talent.
Anub’arak cocoon always causes audio bug in replays : heroesofthestorm (reddit.com)
