Assertion failed: Geometry jobs should not be launched for empty tasks

Just testing out Beta 13 and I am getting the Assertion:

Assertion failed: Geometry jobs should not be launched for empty tasks
Spamming my console, never seen this before in my projects in any versions of Unity, clicking the Assertion doesn’t provide any extra info as to which object is causing it, is this known about? Is there a way to stop it? Finally able to use Unity 2018 now the physics CPU spike has been fixed and now I get this, just want to start using 2018 :slight_smile:

Could you please submit a bug report with a minimal reproduction project and reply in here with the case #?
