So I have this here recipe: https://pastebin.com/X5vEgPG8 and it behaves really weird.

I have the 4 input fluids going to 4 separate tiny fluid hatches that have been changed to have a capacity of 100 bucket (100000mb) and every time (even when I replace them or the fluid sources, or change what goes into which input hatch), the recipe uses:
around 6b of pyrotheum
around 5b of cryotheum
around 5b of petrotheum
around 40b of aerotheum
around 100k total RF (the correct amount)

I tried the same with higher tier input hatches and changing the time to 1s (with the energy per tick to 100kRF) and I got the same result. However, when I changed the time to 4s, it used:
around 600mb of pyrotheum
around 500mb of cryotheum
around 500mb of petrotheum
around 4b of aerotheum

If it just has to do with the limitations of the mod, after spending 6h on the machines alone, for the 2nd time, I won't be motivated to use the mod another time.

Your threat to avoid my mod doesn't find purchase.

However, this doesn't seem to function properly it seems. I'll have a look at it in a few minutes.

It wasn't really meant to be a threat. :P
