This has been an issue for almost a year now and has still yet to be addressed. For the quest in The Cursed Shores where you must escort Warmaster Chan and his group to Anchorage Waypoint, the event still fails to reset properly in the event of a wipe (which is very very often). The Risen that spawn outside of Anchorage never de-spawn, resulting in a huge mass of around 20-30 Risen just waiting to ambush Chan and the players, causing the event to fail and making the Risen that spawned from that run stick around as well.
