I know this is Chia forum and my issue is on Flax but I think it could happen on Chia as well since they share almost entire code (before Pool protocol).

I’m afraid it could happen again since I can’t find anything wrong and it could happen on Chia so I want to catch it before it is too late.

Maybe it is a bug or I’m missing something important.

In my logs I found out that I found a proof and I did not win a block so I investigated and did not came up with concise explanation.

I dug up the exact plot based on “Plot Key”.

I checked that plot against 50 challenges in Chia and 30 challenges in flax and it seems to be fine.

Response time of my farmer was 1.221 s.

Keys are all ok since I’m finding proofs for Chia pool regularly and I found several proofs and won block on Flax as well.

Do somebody have explanation on this behavior?

- Flax version 0.1.0.

EDIT SOLVED:

I got my answer on Discord that flax is only for OG plots.

Still it confused me since NFT can be loaded and checked in Flax.
