Pyanodon's buildings don't emit enough pollution in 0.17 due to Factorio API changes. Let's fix that. Now (nearly) complete!
Despite what the description says, from the changelog it looks like you've decided to roll your own balance instead of scaling Py's 0.16 values in proportion with vanilla changes ?
On second though, you might want to look up at values around 0.17.12, since that's when vanilla pollution was revamped ?
