A recent change (past couple days) is causing PhysicsMaterial2D to appear to be stripped from worlds (perhaps by server processing?).

References to the PhysicsMaterial2D appear to be null on rigidbodies and udon scripts. This only happens in live instances, build and test appears to work fine so I suspect it may be server processing at fault.

This completely breaks the feel and gameplay of my world Melon & Chill suika game.

I need to be able to provide a PhysicsMaterial2D to rigidbody2d and collider2d components so that they have different friction and bounce parameters.

Attached are two videos showing the difference.

My main affected world: https://vrchat.com/home/world/wrld_15f7034a-b074-4812-bfcb-317eaa2741de/info

Minimal Test World: https://vrchat.com/home/world/wrld_1375a8de-bee1-4176-8fb1-72945b0546f4/info

Note that the text below the circles shows "shared mat: null" in live instances. This is a reference to the physics 2d shared material that is being used by the rigid bodies.

In previous versions of vrchat, as well as in build and test, the physics work as expected, and you can see the physicsMaterial2d parameters displayed in the debug text.
