Hello,
I'm trying to start mass production from the warehouse. I equipped four pieces of Venecil costume and equipped an Arbor processing stone on Tri. If I put the material in my inventory, I can start mass production - but not from the warehouse.
System: PS5
OK, I found the solution by myself:
Material has to be placed in the store where I stand before. By pressing "L2 + X" I can select, which work to do and select material(s). Return to store window and pressing "L2 + Triangle" starts mass production.
