My RichAI agent is taking a step up an invisible ledge even though the graph is flat

For some reason my RichAI agent is behaving in a weird way, stepping up invisible ledges with a flat graph underneath. Video here:

Am I missing something obvious?

It looks like you have a hidden collider there.

Oh lord, my GraphUpdateScene collider was getting in the way. Yikes! Setting those to triggers should be still good to go so that the component uses collider bounds?

Yes, a trigger will work fine.
