I'm playing a "vanilla materials" bob's mod game, where I use all of bob's mods except for Ores, Metals and Chemicals and Electronics. With the removal of the separate recipe to make Sulfur from petroleum, and no advances ways of making Sulfur (via Metals and Chemicals I imagine?) there is woefully little Sulfur to go around. Please, reinsert the basic sulfur crafting recipe from petroleum when the mods that add advanced means of getting sulfur are not enabled; this is a crippling issue, as it not only prevents any serious ventures into making a bot network, but it also hampers science and accumulator production heavily. As it stands, I would have to heavily overproduce on raw oil refining and somehow dump (can't even void it without the other mods) the excess heavy/light/petroleum (probably storing it in barrels or something???). Sadly this put my campaign on hold, and I'm holding my breath for a fix. Thank you for your time! (awesome mod btw, once this is over I intend to try out the new metals in a new campaign

TL;DR: When not playing with your modules that add advanced means of getting sulfur, make the base recipe for sulfur from petroleum available.
Edit: I've tried around a little, and upon deactivating bob's revamp I get the old recipe back (and oil refining returns to it's normal recipe without sulfur, which is fine). But I don't really know what else the revamp mod does; would it break something or make reaching things impossible without it? I'll hold off on continuing the campaign for now, I'm afraid turning the revamp off midway might cause problems. What exactly does it do anyway?
