I'm running this PR in production without issues, lgtm except for the minor readability comments.

I know that understand wich one is in hour or minutes is a bit hard in a full number, but the boss time are pretty standard for all boss, so i don't see any problem with that, but i understand you point of view, sometimes a more intuitive script can be better for the user.

The boss is not removed with the room clean, if one player/team fails to kill him the lever will return Someone is fighting against the boss! You need wait awhile. until he is manually removed.

I see where is the problem, the problem is not with room clean, the problem is with the server function roomIsOccupied(). I don't understand why this function is set to return false if there is any creature inside the room, a more useful function would be making this one with more option to let user choose between onlyplayer or not.
