There is some PBCN that is set to produce NEUT in that save.
Oh yes i forgot to set the ctype
Setting the temperature, via console, of yeast to a proliferation-permissable temperature does not stimulate growth until contact with a different element (incl. yeast itself) at a different temperature occurs. This means that [!set temp all 330] (330 being 56 degrees Celcius) in the console with yeast present on the screen never results in yeast expansion. Or maybe this is just my computer being rubbish XD
Try a temperature between 303 and 317 K.
i think this has been reported before but STKM is invisible to WALL.
