I can't get it over 66! The crazy thing is, I can get 30 RF/t from any single wheel in my row of 3, but adding water to any second wheel changes it to 45 and then the 3rd always goes to 66.
I mean, imagine 3 wheels connected to a single Dyname, wheels A, B & C.
I add my water to wheel A, I get 30 RF/t. Looking at the water flow, it is not pouring sideways over wheel B, only down over wheel A. I then add water to wheel C, again no water flows across onto wheel B. Output is now 45 RF/t. Something is wrong with wheel C perhaps - but if I remove the water from Wheel A, leaving only wheel C, I get 30 RF/t from it.
I know my setup is right, it matches the design I've seen in multiple places, and I get the correct amount of 30RF/t from a single wheel, but I always get 45 from 2, and 66 from 3.
Problem I have at the moment is that I can't get the recipe for Red Mushrooms to work. NEI says it's crossed cropsticks over mycelium betwen Nether Wart and Poppies, but it simply doesn't work for me.
