Dynamic Lights are now broken on non-static objects, along with mixed lights

Now, none of my non-static objects are affected by the one dynamic directional light in my scene. I'm using standard shader model, and this worked in 5.3. I'm using the SteamVR plugin on a Vive project.

The weird thing is, sometimes I'll see the object flash lit briefly at certain angles, but go back to totally dark. It seems lighting in 5.4 beta is even more broken than it was in 5.3. Dynamic and mixed lights do not work now. The dynamic light does affect my static objects using the standard shader.

 

This mixed mode lighting bugs are getting ridiculous, I hope these get worked out before the final release of 5.4 !
