Ah yes. I suppose this would have made more since if I had included `EncounterDifficulty`. This is because `EncounterDifficulty` strictly represents very easy to impossible and not the options always or never. So the field `confirmAttackThreshold` really means "at what difficulty do you want to *not* display a confirmation?" In this case, a null value means never disable the confirmation, or essentially the option "Always" and the `IMPOSSIBLE` value effectively means "Never". In the case of `autoAttackThreshold`, a null value means "Never".

On another subject, I guess I didn't scrutinize this patch set very well, as evidenced by the extra space in the `displayLoot` line. :(
