All three mobs types had already spawned previously.

Could the callback to timer(tick) have done line 27 between line 47 and the call back to the function that does line 57?

Haven't tested yet, but that should fix it: https://github.com/BlockMen/creatures/commit/ec83599af3324a05941fd0eb3455f3eea6646ac1

Confirmed fixed, tested with spawn_day=6 and a slightly increased delay on the spawn callback (and with normal values).
