Doing the Mage Tower challenge God-Queen’s Fury has a glitch where, if you’re standing on the circular platform in the center of the room, an invisible ‘box’ of hitboxes closes around your character, trapping them permanently in the middle of the encounter room until you die.
Walking into the hitboxes does not block you, but any attempt of walking out leaves you completely trapped in a 360 degree radius. This happens if you’re standing there after the dialog ends, and can trap you while doing the fight as well.
The entire middle of the room is inaccessible or a death trap due to this, making the challenge very difficult/nearly impossible.
