Adding a probability a log will be shown in the elevator for each log on the floor (only shown to personoids) - nothing too certain (70% could be a likely log for example)
This would allow personoids to target a log with a higher probability to sabotage or target one with a lower probability to lie about it which provides a whole range of extra social deception possibilities e.g. insisting you get a specific log would look suspicious so it would discourage bottling someone to get a log
