Issue with Abnormal Mechanics of Unique Harvest Monsters

When using the Harvest craft with the Level 4 Annihilation Chance modifier, there is a chance to spawn unique enemies such as Danaar, the Omen.
Since the recent game updates, these enemies have become severely problematic. They often continuously attack players for 2 to 3 minutes straight without triggering the Blood-Lock mechanic, which completely prevents players from progressing to the next phase of the Harvest encounter.
This issue severely breaks the functionality of the Harvest mechanic and results in an extremely poor gameplay experience.
We sincerely hope the developers will investigate and address this issue promptly with appropriate fixes to restore normal Harvest functionality.
