Thanks for the quick response and if it’s intended behaviour then I guess just a new design challenge! :) Just to clarify the thing which would be very nice to have (that was working <=2.0.11) is that if you switch between recipes with the same input ingredients, e.g. speed mod 1 -> prod mod 1, then...

I am also seeing this change in behaviour. Previously (<= 2.0.11) if the recipes shared input ingredients these weren't shifted to trash on recipe change which was very nice. Two nice examples which don't work as expected any more: 1) Having a single assembler which could make all types of level one...
