I noticed that composting more than a single compostable causes the Compost to use too much input.
the screenshot shows a compost with polluted dirt, fungal spores and blossom seeds. The tooltip indicates it uses 100g/s compostables while emitting 100 g/s dirt.
What the compost actually does is using 300 g/s compostables, 100 g/s of each avaliable type. I still only get 100g/s dirt though, costing me valuable ressources.

construct a single Compost. compost 100 fungals spores, 100 blossom seeds, and 100 kg of poluted dirt. (or load my attached savegame) observe how all three compostables tick down 100g each second.
