Hi all, something is going on with the latest build here as well, I have a scene which is stucked at "Rendering initial pass" and everything is completely blocked.
Turn off the new caustics solver resolves the case. Is very weird as yesterday it worked fine while I was testing my setup but then I added some new elements in the scene and now is not!!! I am trying to find which elements produce this kind of block.
