Oh, and I noticed that a lot of migrations/conversions are still missing; Bob's Sodium Hydroxide, Oxygen, Chlorine, carbon, and many other materials and chemicals are seemingly randomly left out; all recipe inputs are converted, but only some outputs are. Some stockpiles are converted, but many are left as now-useless products. I know that it's intended to start a new game with Angel's, but it wouldn't take much to make it fairly easy to support dropping it in mid-game. I could make a pull request if desired fixing these; it's not a big deal to write them up.
Just my 2 cents on Petrochem so far. Huge thankyou for all the grunt-work involved in putting together such a huge mod. I can script and program circles around most people, but I just don't have the drive or time to make a mod actually happen while still having time to actually play games
