How were your temps or water? Anything changed on those fronts?
Temps looked fine according to the graphs... Water is RO with minerals added back in. I did add a mash-out to the Edinburgh yeast batch but just went back to the regular schedule (i.e. no messing around with the advanced editor) for the Cal Ale batch. I just added amylase to this batch too to see if that gets it moving again. More than a little frustrated... repeatability doesn't help much if fermentation consistently stops at 55% attenuation!
