Since the new Desert Borderlands were introduced the Asura Gates in the Eternal Battlegrounds no longer connect to the borderlands (or do anything if you walk into them – totally non-interactive), apart from the gate to Lion’s Arch, which still works.
Also, last night I found that the Waypoint for my own borderland was missing… had to use the WvW menu to get there!
Hopefully there’s no way the WvW menu can become bugged, otherwise I’m not going to be able to play in WvW anymore…
