Problem: The input buffer in the cryo plant while using the ammoniac recipe is not large enough to allow the number of crafts per tick the building could do.

What did I do?
I built a legendary cryo plant with crafting speed ~3,000%. At this speed, it should produce 769 ice/second and 7,7k ammonia. I would expect it to produce that much. It doesn't.

I think I narrowed the problem down: At that speed, the cryo plant completes on average ~2.5 crafts per tick, i.e., in each tick either two or three crafts. However, the input buffer only holds less than 150 ammoniacal solution. Thereby, only 2 crafts per tick can be completed. Sometimes, the input buffer drops below 100 (e.g., 99.7). In the following tick, only one craft is completed.

Related observation: the cryo plant is always showing "working", which makes sense, as it is working in each tick. Hence, the cryo plant doesn't show that it is input starved.

Can you please post a save file showing this issue?

Attached. On Aquilo, slightly left of the hub. The rocket fuel factory has enough space in the boxes to run for a while an consume the ammonia.

I attached all three inputs of the cryo plant, allowing to always have above 100 input fluid - consistently doing 2 crafts per tick. But it doesn't go above 150, which would allow the third craft.

Thanks. This is now fixed for the next release.
