Yes, thank you for the update it works now
And just like walkerjonny mentioned, the LV water mills placed before this fix, don't detect water around them ( walkerjonny: they need to be picked up and placed again).
The MV and EV are fine without replacing (didn't test the HV), although I've noticed an increase in MV output to around 21 EU/t, which after calculating the area seems right, but I must have missed that they were producing too little before - around 13 EU/t, I thought it was by design and I didn't count how much it should have been
If the area for MV is 13x13x13 as stated, may I suggest perhaps a slight increase in "internal efficiency", so that it would be more productive than eight LV mills?
