Hey,

I assigne some stuff to upgrade(factorys,belts..) but my bots dont do anything. after some time they may start , but will just do a small part and then nothing happens. see attached scrennshot. bots are there, upgrade assigned, materials are plenty but bots dont´t work

If you want to avoid your issue, do not upgrade anything you lack the items for.
