I'm upgrading to the 1.0 version and I clone the collision world so I can hand it off to a rather long-running job that uses it for a bunch of things. I'm trying to do this with the following inside a SystemBase system...

https://forum.unity.com/threads/invalidoperationexception-when-cloning-a-collisionworld.1391743/#post-9075745

Code (CSharp):
#
RefRW<PhysicsWorldSingleton> physicsWorldSingleton = SystemAPI.GetSingletonRW<PhysicsWorldSingleton>();
#            _clonedWorld = physicsWorldSingleton.ValueRW.PhysicsWorld.CollisionWorld.Clone();

Error:
{code:java}
InvalidOperationException: The previously scheduled job BroadphaserepareStaticBodyDataJob writes to the UNKNOWN_OBJECT_TYPE PrepareStaticBodyDataJob.FiltersOut. You must call JobHandle.Complete() on the job BroadphaserepareStaticBodyDataJob, before you can read from the UNKNOWN_OBJECT_TYPE safely.
