whats reason this blocked submissions?

Your Nature score is double of everybody else... did it maybe blackscreen during the run?

 

For your info normal FPS in Nature for these cards is between 400-460, not 900+... It can happen that it just bugs... not specifically your fault.

no black screen in nature but in trolls lair, nature work fine

It does not need to be black screen.

Sometimes it is stuck just before the butterfly lands and still shows a score, but it is inflated as in your case.
