Few days ago Blizzard fixed Opera Hall: Westfall Story bug with Toe Knee.
Until they fixed it, the problem was when you killed Toe Knee too fast (usually with high gear character) he just died and Mrrgria was stucked on 1% and fight continued.
After many years Blizzard fixed it BUT now you MUST kill Toe Knee before he go to his invincible phase.
If you can’t oneshot him, he will stuck on 1% in the last phase where you fight both bosses.
Old bug was annoying but it was doable if you took off weapons on max lvl char. Low lvl char (around 50-60lvl) had no problem with this.
BUT! With new bug you can complete boss fight only with high lvl char beacuse low alts dont have enough dmg to oneshot Toe Knee.
I’m faming Midnight mount on 14 characters and now only 3 of them was able to complete this.
Dear Blizzard, can you please fix it correctly or just return old bug? It was annoying but at least killable.
