Bugged boss fight

Basically I was doing The Jade Isles boss map, and at 2nd phase, on the way there were some delirium mobs I lured into the hallway to the boss, but boss also took agro as a delirious mob with delirium lightning spirit on it in a T pose and arena closed before I reached it. I recorded a video with exact explanation, here is google drive link: https://drive.google.com/file/d/1wfl4x15Wq2YNTpoPE746ttlLxnj1cQQ0/view?usp=sharing . I lost the map and let me guess, there will be no compensation for that, right?)))
