Thanks for the input!

I have updated and tried rendering again with similar results.
I have attached log, but I cant translate it to anything understandable in regards to any error :-/

I have created a growing stalk and leaves with Mospline and deformers.
I have made instances of the original plant/stalk and had to set them to Render Instance to avoid funky things going on with the objects (probably because of deformers using world space or something).
