Guild Wars 2

I will try not to rant . . too much. But I worked a Dragon Stand Map from start until 1 minute before finish. During that time I disconnected three times, the last one fatally so since when I logged back in they finished the mouth and I was left with Jack to show for the time and effort. I am certainly not the first to have this problem. I have had a difficult of a time even making it into an organized map and then to be deprived of what I had worked hard to earn is just wrong. Here are the error messages. Fix them. Sorry, that is about as polite as I can be at the moment.
