This happened to my and my husband as well, he was a 31 human engineer and he progressed to the next question a fragile peace and I jumped to forewarned is forearmed, he was the instance owner. I was a level 30 elementalist, we were both order of the vigil.
It doesn’t need to be said however I will say it anyways that this is not acceptable in any form, if I wanted to spend 17 levels plodding along with no arching story to go through there are plenty of other games that could give me that, and alas the pledge that it will not happen again once I reach 48 is only as good as the intent that it would not have happened in the first place.
