Hi, I run a small guild and just bought GW2 about a week or two ago, and one of the first upgrades I went for was guild workshop. Guild workshop worked fine the first day, built both art of war and architecture lvl 2 at the same time. One of my officers then began upgrading guild stash. After the recent update, the progress on guild stash was at 0:00 and stuck so I had to cancel it on queue, and then I added both guild stash and art of war lvl 3 to queue, but only guild stash began upgrading and not art of war. Is guild workshop a one time thing or is it a permanent upgrade?
