Quite a serious and easily repeatable bug where I softlocked myself during the quest “Saving Last Refuge” by defeating the boss and portaling to town to clear my inventory before interacting with the shard. Upon coming back, the elder was there overlapping with the shard, and the path was blocked. I interacted with the shard and the path remained blocked. Spoke to the elder and resummoned (…only phase 1 of?) the boss, defeated it and the path remained blocked.
I was able to resolve this by relogging and defeating the boss once more, however it did progress the quest when activating the shard and softlocked that instance.
