SCI: SQ4: Sock's door not redrawn, no message (CD version)

[sluicebox]

The door to Sock's clothing store in the mall has bugs in the CD version. It isn't redrawn when restoring a game and it doesn't respond with its Look message. This is due to a script bug which immediately disposes of the door after adding it to the screen.

To reproduce with attached save from CD version:

1. Wait a second for the conveyor belt to take you to Sock's
2. Look at the door, the door message isn't shown
3. Save game
4. Load game, the door is gone
