DCing on Hilla's bonus stage (Dimension Invade)

Describe the problem. Be as specific as possible!:
Everytime I'm sent to Hilla's bonus mision and get to fight his pet I dc, is it just me or everybody else is going through this?

No images

same not just you

Ok so Black Heart I noticed 4 attack patterns

the regular attack with the healing symbols around him
the orange fire breath
a purple magnus looking aura
a purple Reflect cast

and there is a forth one that he casts causing me to maple crash

Yeah just crashed twice, while fighting blackheart

yep, same thing happened to me.

I crash the moment the stage starts, I don't even get to attack blackheart.

(Also I believe Hilla is female.)

Try not spam clicking npc chat through hilla's dialogue.

Helped for me.

It's happening to me as well. In a party of 4, everybody crashed around the 80% mark. It's hard to see an attack pattern with everyone hitting it at the same time.

I'm fairly certain, with my statistically insigficant sample size of 4 people, that dimensional invasion is a hacker trap.
More specifically I'm talking about the Hilla Darksoul bonus stage, which is only accessible if you complete the main quest within 10 minutes.

My legitimate friends and I experience client crashes just past the dialogue with Hilla, before the darksoul battle, whereas certain people I occasionally associate with are able to bypass the dialogue and fight and kill darksoul to get the necromancer boxes.

Helped for me.

I still randomly d/c during the battle.
