Bug : door closing on player (he should die?)

[Georges]

Right at the start of the game (in map bm_c1a0b), after passing through the corridor with the two red laser beams at the right, there is an automatic door which opens… And if you get in its way when it closes, that traps you into an invisible jail; without killing you… Therefore preventing you from going forward.

In other parts of the game, if one of these double doors closes on the player, the rest of the map disappears as if the door was closed.
