Small bug

[crowz9]

I installed a custom story today called "Survival".
There is some sort of glitch with closet doors.
When a monster is smashing at the closet's door I'm hiding in, I think it would be a good idea to bust the door open and run away. Press the right button to do such action and all of a sudden the game crashes and works at 1 frame per minute.

After several frames, there's dust around the door and all objects of the room are flying. I wait like 10 minutes until the monsters kill me.
Once respawned, BAM!
All the doors in the map are gone. Including the ones that the monsters didn't smash into pieces.
Also the drawers are gone.
This doesn't bother me at all. In fact, It's funny as hell. I saw a playthrough on youtube, and the same thing occurred.
Has this ever happened to you?
What's the explanation for this? Is it a script hole or something?
