Guild Wars 2

I choose Carnach and Caithe to bring with me.
Canach goes fine,the rift updates,and we proseed.
After the paile tree is dead,I try to update the rift,but nothing happens.

So the story stops there..
Played it twice,same thing happens.

Got this yesterday.The I got it achiv.
Reason why I post this it happened in the last phase.
Teq was less than 25%,and the zerg was moving in for the final attack.
I dodged in between his to front feet,while meleeing him,
and suddenly I was dragged under.
Didnt see any whirlpools tho`,too much people for that.

This was a full map with 3 comms.

What the op says,game have became very laggy last couple days,makes it unplayable.
Never been an issue before.
