GVR Reticle Not Expanding?

I have five scenes where it's working perfect - and this one that it's not. The red dot appears but does not expand when over an object. I have checked and rechecked and cannot figure out the problem. As a test I just have a sphere with a sphere collider and a EventTrigger calling a look at method in my manager. Reticle distance is good, debug rays are poking through the sphere... reticle expansion rate, size etc is the same as in my other scenes. Tried deleting all the GVR components and replacing them... Camera is tagged as Main.

Is there any kind of scene setting that would disable events for the reticle? I could live without it expanding today but I really need events to work so I can get this scene working.

 

Somehow I must've deleted the gvr physics raycaster script from my camera. No idea how I managed that, but that was the culprit.

 

Do you find any solution
