Nightingale PTR Portal
After going through a broken wall section (image) near Blanche's medical tent to find a chest, the interior of the room gave access to the inside of the building that should not be accessible (image 2). Going through the building it is clear this area was not supposed to be accessible (image 3).
Building is slightly offset vertical to other buildings. It appears to be floating when looked at from the back. Looks like the offset was intentional to go with the street, so changing the terrain in back should fix it.
Under the bridge with the Nightingale City Well Gate zephyr there are unsightly structure protrusions and openings into places that shouldn't be open.
The edge around the Crystal Palace is open to the underworld. Not enough room to get through, but visible.
There is a missing foundation tile on the western side of the Crystal Palace that leads under the ground, and connects to another location where there is a gap in tiles.
In the Crystal Palace north entrance there is a glass tile with vegetation on top. The bottom of the tile appears to be incomplete, creating the appearance that you're looking through a tile from inside of it; the glass should be less transparent.
In Queen's Brae, the tall structures holding the bright lights are immaterial at all altitudes.
In the fae ruins near NTTC, the bottom level sounds like water when the floor is attacked. I attacked walls and the upper level floor and they had the "broken glass" sound, so it is only the bottom level floor that has the water splash on top of the "broken glass" sound.
More anomalies, Isle of Dee
"Empty room" was blocked by a destructible door, was probably meant to have stuff inside.
Queen's arena "Immaterial pillars" are for all pillars, including the smaller ones.
After beating the Crystal Palace the Pale occasionally hits. It is rare, and I can't get it to repeat in the same location twice.
Missing wall in the sewer and other anomalies.
There are various fake floors, invisible walls and other anomalies around the Cathedral, including its scaffolding. Too many to reasonably identify them all.
A small opening where there should be a solid wall in the Fae ruins beneath the Bastille of Might.
This hole in the wall allows players to drop down and take two options:
Move forward through a passable wall section towards the water
Turn around and walk into the world.
If the player goes through the passable wall there are other walls along the water that players can move inside of.
If the player turns around the dirt hill leads into the ground of the city, where there are several more sections of the wall leading towards the water; they also have passable wall sections near the water.
In order to exit the area back to the normal city the player needs to use the grapple function of the climbing picks, aimed at the ceiling near where they entered, and then exit once they are at the proper height.
More locations with improper access to building interiors, or missing graphics, or improper baking (passable walls).
