What I was doing: Entering a naturally occurring (non woven echo) cemetery in single player online
What happened: The Cemetery was impossible to complete
Occasionally when entering a cemetery the mini map will not be aligned. When this occurs, it creates an anomaly where when defeating the boss, the reward area is inaccessible, the quest objectives leading to finding the boss do not resolve, and the echo cannot be completed. The barrier is clearly visible, and the quest objective after finding and defeating the Woven Firstborn still states to find the boss. When leaving the echo and reentering the issue persists on the echo, and once before it affected an adjoining echo. So far this has only occurred for myself with cemeteries, not tombs, and only the naturally occurring cemeteries. I have not encountered this bug with the woven echo version of this instance. This will be the fourth time the bug has happened across a large number of experiences.
I do not have an account to upload images to a separate site to then link them here, so if you need screenshots a moderator can contact me through my account email. I have submitted a bug report in game with the data and a screenshot attached of the entrance visibly showing with no other map features. Good luck!
