i've stumbled upon the factory not recycling sulfuric acid, yet the input is filled with 1k of it.
Deconstructing and placing the factory starts her right up.
All other in and outputs are displayed as empty.
Even the Info while mouse hovering over talks about no ingredients.
Sorry if i'm at fault but i'm sort of lost on this behaviour.
Hm, that's odd... loading up in vanilla v1.1.27 and sulfuric acid recycling works just fine. I would wonder if the sulfuric acid recipe has been changed or removed in your modlist?
But if it works when you unbuild/rebuild the machine, then that seems like the output recipe is too large for the output pipe (which shouldn't normally happen, as the output pipe size is 1k)
Hm, it might help to know if any big mods are in play, so I can try to reproduce (especially if it's inconsistent). Anything like bobs, angels, space exploration, industrial revolution, or pyanodons mods, etc.
