Staircase Glitch - Found by Konaruhi Thread - The Bad Birthday mod for Amnesia: The Dark Descent

Konaruhi wrote: I found a glitch. As soon as you start, if you walk between the wall and the staircase (ONLY the right staircase, the left staircase doesn't have the glitch), you'll just go through the staircase completely. The game doesn't crash or anything, but you can probably walk though the staircase and a wall to get into the nearest room. You can also walk back out, so it's not like you're stuck there or anything.
I made a video that shows me exploring the glitch a little more in depth. My hypothesis about being able to just walk into the nearest room was incorrect, however you can still interact with things in said room, like opening/closing a close closet door, which is shown in the video. (I did some tests in the video, such as testing the other staircase, seeing if I could walk out another way, and things like that.) Youtube.com

I messed up a bit on making the forum listings. Now you make a new post instead of replying to the one I had made. I quoted Konaruhi here for this bug.

I also found out that you can actually take things with you through the wall too. I was holding a chair and went through the wall, and I was still able to hold onto the chair. You can also lay down items within the wall too, but you can't pick them up after you set them down. The items just become stuck to the floor within the wall.
