For patch #4/5
1. These stairs are still not usable. https://postimg.cc/Z0RkdCss
2. After collecting all of the Queen's Gems and then placing them to open the door, I can't enter the room.
3. At the start of the Steam, the front of the steam is animating backwards but still takes you down. Also, the player can jump across the steam. https://postimg.cc/nXRtZR5f (it may take a while to load)
Also, when I saw "Added more dialogue", I thought there were new interactions when having Polly in the team for Floater's Forest and/or Seal of Flesh, but it turns out the more dialogue was for the new bosses instead.
