Smart Observers crashes when observing Cauldrons from Amendments

[Rebuild3]

Context

Placing a smart observer facing a cauldron that becomes an amendments cauldron will crash the game.
I used the cauldron to craft a soup item, and attempted to use a smart observer to stop the deployer placing water and automatically trigger the droppers to put items in the cauldron.

Could you report this to Amendments, too? This seems to be an issue with how they represent their custom cauldron, as NeoForge seems to be the one failing (it can't find an actual vanilla cauldron)

Can also just reproduce this by breaking a vanilla cauldron from in front of a smart observer. Inclined to say this issue would be fixed if that were fixed.
