AI character freezing

So after getting some weird results setting up my own path finding AI script, I discovered that there was the AIPath script already written. I have on character moving to a designated stationary waypoint, with a second chasing the first.

The second character who has the first character set as his target stops moving pretty regularly for like a second every 5 or so seconds? (The first character moves continually)

I can’t work out why this is happening?

Hi

What is the repathRate for the AIPath components?
The repath rate determines how often it should look for new paths.
