RVO avoidance not applying

Hi all

I have some enemies chasing my player (top-down shooter) with RVO avoidance checked but they aren’t avoiding each other at all - their movement doesn’t change whether I have this option ticked or not, and they continue to overlap.

I’ve looked at the groups and they are set correctly to avoid the group that they are in. There doesn’t appear to be any other additional set up that I should do in order to get this to work (based on the tutorials I’ve looked at anyway).

Any ideas?

Figured it out. My enemies are set to be Flying… changed to Walking and it all works fine.
