I have re-designed my synth network after resetting it - I play in Genesis.
In total I had 12 tiers.
I converted 10 of the green cores to a blue core. The other green cores I placed on for example increasing total production.
When trying to place the blue it is greyed out and keeps indicating I need 8,000,000. I don't have anything near that
It also shows it is available but not used:
Must I first amass 8million synth energy before I can use the blue? Or is there something I am missing to place the blue on one of the selected nodes - if I am missing something can someone please provide a step by step guide how to actually deploy the blue core
I also tried on points where I added the green nodes and where there were no green nodes - no success.
If I cannot use the blue, I guess I should downgrade the blue back to 10 green ones and distribute them across my network.
