Glitches

Formerly thought of as glitches:
 * A crash during the cutscene on floor 1 with the trader caused, on reload the trader to still be there. The trader was holding a golden ticket which the item said we weren't supposed to see. While the crash was unintentional, you are supposed to be able to dodge the cutscene and talk to the trader (think: stealth). An achievement is linked to this.
 * The glitch door, which is linked to an achievement (See the page for achievements for more information).
