Requiem: Bug with opening drawers

[Keth]

Another bug while opening drawers.
On the beggining I could open all of them:


but then after closing all, two of them on the top stucked to each other and I coudln't open them anymore (I spent like 5-10 minutes but no result):


Then I have tried to open them by throwing a book and hitting the drawers but then it went worse like this:


Two of the drawers on the top just moved backward and got stuck even more.

I'm sure that you guys know which blue lasers I'm talking about.
On the beginning of the level the weird waving on the top wall (I guess it supposed to be like this) and the blue lasers above.
First crash, I have been randomly clicking the red buttons (in-game) on the ground and after like 5-10 seconds the freeze came.
Second crash, I haven't clicked any buttons this time but climbed up the wall and after I went through the blue lasers imidiatly game freezed.
Third crash, I climbed up again and I saw my FPS decreasing (like 5 FPS per second - I had 60 FPS on the begginig). After reaching 15 FPS the game suddenly freezed.
Fourth crash, SOMEHOW I managed to get on the lift (still near the blue lasers) and one more time game freezed when my FPS was low.

Basically it's impossible to complete this level because of the freezes or crashes.

Due to the freeze I coudln't manage to catch the Black Box (because Penumbra was on the top).
Luckly, I did this screenshot of Black Box:


Luckly, these drawers were empty but they could contain some important item.

I'm really waiting for the fix because I love the game.

I was bored waiting for the patch so,
