Game Breaking Bug (Spoiler)

[LazyFly]

The game does not normally allow the player to move on to the next "level" until the current level is absolutely completed, which was a good design choice considering you can't very well go back in time. There is however one exception to the rule and if you don't nab this particular item you won't realize that you made a mistake until you need it far later in the game.

Since I wasted about 5 hours due to this bug I figured I'd post it here so it doesn't happen to others, see the spoiler below.

The item is a "Photo of a Pretty Young Girl"- it is found in the powder room of the estate on the first night of the game; it is stuck to the mirror in the first area of the room as you enter. You are required to present this item as a "hint" to Lavonia towards the end of the game and without it you simply cannot progress any further.
