Magatsu Urgent Quest disconnects me almost all the time

Whenever I play this certain urgent quest it has disconnected me many times. It has disconnected me from the bosses before the final boss's urgent quest and from the final boss urgent quest. The last time I got disconnected was when I pretty much gotten robbed from defeating the final boss on the hardest difficulty and didn't get the loot since it disconnected me before I can even get the loot (as shown on image below). So it was pretty much the last straw for me that it kept disconnected me from this urgent mission. I have no idea what's causing this to happen for this certain urgent mission and I really want it to be fixed. alt text

I'm also having this issue. I submitted a ticket. Its frustrating to clear all three magatsu and get dc'd.
