But..but.. Their first order is already unload, and their second load.. That would be the logical order for these orders, to prevent them getting stuck on loading.
But it doesn't work. It looks like, the secondary 'pickup automated mine at population' order does not remove itself after completion, to make room for the primary 'deliver automated mine to mining colony' order.
I am talking about 'default' orders (the 'primary' and 'secondary' orders, above the 2 conditional order tabs), not about manually set orders.
I just want to have them continuously pick up a mine from earth, deliver it at a mining colony, pick up mine from earth, deliver at mining colony, etc. etc.
