Describe the bug
I'm playing on FTBPresentsStoneblock2-1.16.1-1.12.2 and placed down a herculean flux storage cell obtained as either a quest reward or a loot box, not sure as I found it whilst transferring chests to an ME system. Once placed and connected to the network, all connections isolated themselves. My inputs showed power addition from my bank of magmatic/draconic evolution generators and a separate input for my extreme reactor that has function for two days. Turning off the reactor then isolated the plug to not receive power anymore at all.

I've troubleshot the system by removing and replacing items one by one and attempted to create a new network as the next step but the create network button is greyed out. Deleted my network to see if that would eliminate the create issue, it did not. Then removed all flux items and destroyed them, deleted the fluxnetworksdata,dat file and tried to create a network from scratch and still couldn't create a new network.

I can provide three different save points upon request if needed: one after giving up on problem solving last night after removing and deleting the herculean storage didnt help, one after burning all flux parts but prior to deleting the fluxnetworksdata,dat file and one after deleting said file.

As a side note I have crashed the game a few times when creating a new network with no others by clicking the hyperlink text for creating a new network rather than the button in gui.
