In the new patch, the characters have a strange perception of beams and wooden decks, on which they used to calmly walk and jump. Now almost always the jump "ignores" them, offers to jump down somewhere, or it is impossible to reach. This bug can be most clearly seen in the Shattered Sanctuary, a locked room in the western part of the map in front of the Infernal Shrine.
I felt patch 9 was worse at handling verticality, too, and that I was too often accidentally clicking on the wrong level for movement and jumps. So it’s reassuring to hear that it’s not just me and that there may actually have been a change in the game that can hopefully be fixed!
