Resolved Custom mesh collider not colliding with other objects

Hi all,
I'm making terrain which is generated at runtime and have a number of mesh colliders generated in physics collider components. I know the mesh colliders are being generated properly using the physics debug system, however, no other objects can collide with my mesh collider, they simply pass right through. Other objects can collide with each other, but nothing will collide with this... I've taken care to make sure my mesh collider entity has all the components as a test physics collider I converted has - no dice. Does anyone have experience with this issue?

 

Updating to the latest version of DOTS Physics fixed this issue.
