Not sure what sort of solution is going to be offered, but an in-game system letter after reaching the point of no return should have been sent out with a “under construction” message.
As is, I’m one of the new players to GW2 who is now well past the point of no return because I never knew it was an issue until today (just thought the story editing fit the $10 price I paid). A simple message could have prevented this for myself and others.
I am presently surprised at how much I am enjoying GW2 in general. I just hope basic quality control/project implementation collapses like this are the exception, rather than the norm.
