I saw that the lifts in CoC were still using a script that lets the lift pick up all nearby Creatures when activated by a Creature, like in the original Creatures 3. If you can, may I advice using a script similar to lifts.cos in Minor Fixes? http://creaturescaves.com/downloads.php?section=COBs&view=745
