I must start by saying I love scavenger hunts and this command; that said though...
Bug? : /event command is not listed by the /help command in chat.
change: /event already counts time until drop (after map announcement); It would be nice if it also told the time until the next map is announced rather than "unknown"
another note about /event : perhaps a notice during events when players log in that /event command exists would be helpful.
