Hey!

I found something weird. The catalytic cracking of naphtha to propene requires green metal catalysts. It then outputs a 90% chance of a red metal catalyst and 10% chance of en empty catalyst.
- In my memories this is supposed to output a green one (as in, 90% chance to retain, 10% chance to consume).
- The red metal catalyst doesn't exist according to FNEI and the tech tree. This leaves an unusual product as a result.

Hi,
Thanks for your report.

Angel's 2.1 made catalyst recipes return their catalyst (90%) instead of always using it up.
Sea Block moved catalytic naphtha cracking from red to green, but only on the ingredient side, so it gave back the hidden red catalyst.

Fixed in 2.1.8: every recipe Sea Block moves to another catalyst now returns that catalyst. Green, blue and purple catalysts also cost 1 carrier each again; they had accidentally gone up to 10.
