@. oh yeah I have seen some of my geometry dissapearing which was really strange. I fixed the particles just by converting them into GPU particles. Anyways I have encountered a bug in my branch while using Volumetric Lighting and Depth of Field which I guess is because Volumetric Lighting is blended on top of everything, but it actually should be below stuff like Depth of Field.

Can anyone confirm if is also a bug in original Volumetric Lighting branch?
