I'm doing the following macro with a food/chem tool and for some reason I keep getting a "crafting session has ended" message. It does this no matter what I try to make. I have tried adding a third /nextCraftingStage before the prototype but that didn't work either. I get the error right after I select the resources. Anyone have any ideas on this?

/ui action toolbarSlot00;
/selectdraftSchematic 08;
/pause 5;

/nextCraftingStage;
