Help with Pathfinding

[PKirkby]

Hey everyone, I'm having a heck of a time with the AI of my enemies. I have a simple ARPG format, and I want the enemies to follow the player to attack. This works mediocre at best with "move towards player" from movement route. I have the smartPath plugin AND Galvs Event Detectors, they both us a pathfinding solution, but as soon as my enemies get to the player, they start to lag out hard. I've narrowed it down to the pathfinding because when I remove it, it's fine.
