The first hydrogen plate spoilage was a bit of a jump scare :).
I'm having a bit of an issue with sulfuric acid production though, mainly due to water. Given that sulfuric acid is required to make water (to make the alum) and water is used to make sulfer and sulfuric acid, the cyclical nature of it makes it really hard to balance. Water is also getting sucked up by power, steam production, and heavy oil processing, then heaps of carbon is required for all the planet-specific production lines (which also needs acid). I can't get consistently working production of everything without shipping in carbon, sulfer, and ice from space. Which is fine, but I'm not sure if this is intended, or I'm just doing something wrong. To be fair I'm more of a "just add more production when I see a problem" player than a "meticulously plan out ratios" player.
Very fun and unique either way, particularly the hydrogen plate production and usage of it.
