Harvest Boss. (Not Phasing when HP threshold is met and Yellow Beast Grasping Vines).

Pretty often there is possibility that Harvest Boss (T4 seed) won't phase when HP threshold is met (it's when it becomes stationary and summons monsters) instead it locks itself in ability usage and spam those (most noticeable is Yellow beast stealth jump),but phasing is still possible. (it's forceable by leaving Boss argo range.) (You can understand that boss is phased when Mark Curse dissapears from it.)

Also, if i am not mistaken Yellow T4 seed Grasping Vines shouldn't apply can't use movement skill (the circle mechanic) if i am not mistaken it was changed in 3.18 so players would be able to use movement skills, but now it still apply can't use movement skills.
