Occasionally you will get stuck in the "door" upon entering. I don't know why this sometimes happens. You have to jump once or twice to free yourself. Only rarely did I have to teleport out or to the chamber door. Fixing it would require moving the door and walls which would throw off the whole build and it was too far in for me to want to attempt fixing it. I'm sorry for the annoyance. It's mostly fine though.
Edit 6/1/26: I noticed the door frame was ever so slightly off so I straightened it.
