Graph / obstacles ignored at run time?

Hi, when I scan the graph in Editor mode, it seems OK, but when I hit play, some obstacles are not recognised. The desks, walls are both set as an obstacle layer.

Any advice?

That’s odd. Do you have some script that removes colliders from those objects?

No script that removes colliders.

I’ve just pressed “Generate Cache” and that seems to have fixed it, never had to do that before though.
