Guild Wars 2

So today i decided to go to ascaleon catacombs with my friend.we went explorer and We choosed path “2”. we got through the dungeon and were ready to fight the last boss, the ghost eater i believe he is named. Anyways before you can fight him, you have to do an event frst, protecting your companion while she is repairing or charging 3 traps, but she would only stand there, not moving or doing anything. We spent about an half hour trying to figure out wat was going on, but then the rest of our party lost patience and left. I got really frustrated over this and i know that this is going to be frustrating for others aswell, since we used a good portion of our time doing this dungeon, all or nothing only a bug.
I sincerely hope this will be fixed and i made this topic to shed light over this incident.

I can attest to this. Same bug happened to me twice in a row.
