Void Tower Raid Waypoint Bug

[kubbi]

So it happened twice to me so far that the waypoint was wrong. Or the map could be wrong? The waypoint eventually shows me to a dead end. A treasure room for example. So it doesn't show the way to the objective or the map is loading wrong I don't know. I ended up having to quit the mission or ending the game and restart.

 

I know there can be several other routes to the objective but I am sure I took the right route. There weren't alternatives either. I tried finding my way without the waypoint but that didn't work either as they also end up in dead points.
