Please check Taken Blights. Seasonal Grandmaster Whisper conqueror challenge is next to impossible as Taken Blights can't be destroyed, stepping into one (first room) means insta death. Funny or not funny enough the Taken public event in the Dreaming City suffers from the same bug or feature just to a less extent. Here it takes about 3s to be killed by just running into/standing in a Blight. Intentional?
