Factorio Let's Learn Bob's + Angel's Ep 88: Red and green catalyst filter thingies
We're still hunting titanium but need rubyte crystals for it. These crystals need nitric acid which, unlike a lot Bob's and Angel's items, only have a single path to production. This path requires both red and green catalysts. We've seen these appear in FNEI in the past but I've always skipped over them as there were alternatives. Well, now we're forced to build them so let's have at it.
