Christmas bakery
Christmas bakery T2 does not work on Improved Silo. The building gets buffed but it stops replenishing fields.
I have 8 T5 Improved silos covering 9 T4 Improved farms with close to 1:1 production time (IE: my fields should never die).
I Guess 1 divided by 2 changes the input from 1 to 0 instead of 0.5, which in turn stops the output.
I would assume that any 1 input building (Fish farms, Deerstalker huts, etc) are effected aswell.
