heheh.. that's because the game pretends that the only thing that changes when you leave a loadpoint (eg, world -> fargrove, fargrove -> world, world -> some building in arindale, etc..) is the sky the game script - the game timers are relative to the time spent in the area.
Sometimes there's item clean up or npc's repositioned by the script when you load... but that's really only applied on the outside world and in messy dungeons I believe...
Perhaps there's a way to use this to your advantage though..
By spawning one inside a dungeon, walking out, recharging, going back in, spawning another, etc, up to 500 bazillion creatures or so, and upon judging you have enough, swarming the dungeon and it's bosses with them.
