I don't understand how to get a Geological core.
I arrive at the resource field. I set up a Core-drilling rig.
A second later, the field changes to a specific resource. The Core-drilling rig starts flashing the "no resource" icon.
But at the same time, no Geological core appears.
What am I doing wrong?
