Guild Wars 2

So on Monday I was doing Dragon’s Stand. Everything worked and went as usual, except for the Vine Growths during the last Boss fight. As you can see on the Screenshot, the Vine Growths were permanently visible on every island, but were not targetable. Their events did not trigger even once during the whole fight. Anyone else had this?

Haven’t see it yet but I saw someone mentioning it during my previous run. They aren’t targetable since they aren’t actually there. It is some sort of visual artifact.
