2. Party member in 3 part alliance used a bard song, crashed all of Abyssea - ALtepa
3. Logged into FF11 on roomates computer who plays ff11, and crashed all of selbina.

In depth explaination from previous thread I made about this:
This started on the 8/24, when I was in the Eastern Altepa Desert, where me and a friend were leveling, and we found a NM, it used a ability, and my and my friend both got d/ced. At the time, I though it was just everyone in my party.

The next day, 8/25, I was trying to break my limits for lvl I think 80 in the Ru'lude Gardens, and I was in the cutscene, and I was with a friend who used the bard spell which increases movement speed, (can't remember which one that is), and it crashed me and him. Once we logged back on, thinking it was a fluke, after I had to re do the cutscene to break limit 80, he did it again, and once again we got d/ced. I quit playing for the day,thinking it was a bug that would be fixed soon. The next day afterwards, I was contacted by a gm, who thought I was stuck inside Ru'lude Gardens. I told him what happened, and said ht was going to contact the software team about the bug. On 8/31, I was inside Abyssea - Altepa, and was in a xp group, and in the alliance, we had a bard who casted a bard spell, the whole alliance, and the whole zone went down.
Afterwards, I used another computer to test this out in Selbina, and we crashed the whole zone of selbina, and was confirmed by someone who wasn't in our party. I went to technical support, and they told me to post on the forums, so here I am. My game is now unplayable.
