Guild Wars 2

Started doing Gates of the Maguuma i have got up to mission cornered and cannot get any further.
I kill the sabotuer at the end and a dialog start between the party and the master of peace it get to the bit where he says the saboture went mad on the ship and thats it ether dc to char select screen or complete crash black screen happened 5 times now really annoying on top of not being able to finish personal story because of the cannons bugs.

Still getting this bug really annoying 15 time ive tried to do this mission and everyone failed.

Still getting issues with this season 2 issue cant progress any further is this being looked into?

Also have another charture on my accout who is up to Into the Labyrinth mission got there a while ago went to do the quest and same thing happens when the master of peace speaks after the boss kill D/C black screen or crash out completely
