Something is wonky with the richness scaling in the Zircon patches.

On default settings it is roughly on par with other resources relatively close to spawn, but overtakes them about 1000-1500 tiles from spawn. Around 2000-2500 tiles Zircon is reaching 50M+ per patch while other resources are mostly in the 5-10M range. And it scales further out of control from there.

Maybe a side effect of lowering richness in the starting area?

Thanks for the report! Fixed in latest.

Yes, you guessed it. I accidentally applied a lua not to a noise expression. Of course, instead of negating the noise expression, that turns the noise expression into a lua false. I then passed that into a noise if_else_chain meaning it would always return the "else" value (the scaling value).

It's very easy to make silly mistakes with the noise library :)
