Guild Wars 2

The string of events for the door leading into the Infinite Coil Reactor seems to be bugged. The door wont open and I am not too familiar if there is another way or is it just glitched.

The door is only open during a small phase of the chained event. Not sure how long the timer is. There is no other way unless you are an elementalist if i remember it right. (Some odd stunt using lightning)
