tl;dr version at the bottom

Apart from a few strange reactions, and lack of some important ones, the thing that really bothers me is strange progression paths for some liquids. I use two of these in my playthrough: firstly you can get nitric acid with lv machines, but there also are other recipes for hv machines for both ammonia and nitric acid. And it's not like doing that way is cheaper in terms of energy, quite the opposite actually. Then there's also acetone bypass. When you get calcium acetate solution, I think you are supposed to distill it with eiher an mv distiller or an hv distillation tower, but you can instead use lv fluid heaters, which would do the job faster and save energy. Finally, I wanted to exclude any weird reaction from this post, but there is one that is just bugging me too much - when you use hv+ pulverizer with end ores, you sometimes get end stone dust, but it is different from the one you get from straight-up macerating end stone, so when you need to make end steel you can't use it, you need to go ahead and macerate end stone, despite the fact you already have a lot of end stone dust, just not the right "type".

1. There is no advantage to using hv machines over lv machines for creating nitric acid
2. There is no advantage to using mv/hv machines over lv machines for creating acetone
3. There are two types of end stone dust, and they aren't interchangeable in ordict
