After placing I connected the red circuit with a roboport and marked 'read logistic network contents'e
The statement 'advanced circuit < A' with A = 15 000 and advanced circuit -10 (because shortage) is false (red light) on all inserters. (not correct obviously, they should be working)
After removing, replacing and reconnecting the inserters manually, they start to work like they should. (the statement is true; green light)
I had two mods (Miner planner, UPgrade Builder and planner), I uninstalled them, the problem persisted and this is the save I have attatched. (so no mods enabled).
Have fun

And lovely game once more, nice job guys. Really looking forward to version 17.
