BUG in Endgame： Manoki can't change to the second status

Hi GGG,

In The Jade Isles,
The BOSS Manoki was stuck in status "The Chosen",
He just stands and doesn't change to the second status "The Fevered"
(The skill I'm using is essence drain & dark effigy & contagion)

Now there is a RED "FAILED" MAPE NODE IN MY ENDGAME,
that makes me feel really upset...
