After setting a recipe in a machine with a product or ingredient that can spoil, the recipe tooltip shows what spoiled items this building might produce right below the 'Total raw:' section. However in the 'Copper bacteria' recipe, copper ore isn't listed. Same for 'Iron bacteria' not showing iron ore. I assume this is because the bacteria isn't a guaranteed product in these recipes.

From a quick check i can see this behavior can be explained easily: trash items are generated as any direct or indirect spoil product of item ingredients. In case of this recipe, bacterias are only seen on products side and as such they are not covered by the trash items. Question that will decide if this is a bug or not is what was the intent behind list of trash items.

Thanks for the report. Issue is now fixed for 2.0.69.
