What did you do?
I connect a roboport to the circuit network with a green wire (from the roboport to a pole).Then I click on the roboport to open its GUI. The circuit network's checkbox "Read logistic network's content" is already checked.
What happened?
When I click on the other checkbox ("Read logistic network's stats") the first one is automatically unchecked.And vice versa. It's seems that I'm unable to check simultaneously both roboport circuit network's options.
