If you use ExNihiloAdscensio and ExCompressum, than the hammer registry is another function.

Here is the crash log.

Can you fix that?

I will think about it, I don't really want to add support for both versions of ex nihilo.

Couldn't you use the ExCompression API? There are both implemented.

I can (and I did) use it for the sifting recipes but there is no api for hammering recipes.
