If you use a EnderIO storage or any other storage with a real value of rf, the flux network wont work with any storage larger than 2.147.483.647 RF. The Storage CAN be larger, but as soon as the storage reaches the fillstate of this RF amount it wont transmit any rf and if u click on it the max send is a negative number.
I guess it must be a kind of overflow with the fail, that he calculates with int and not with long or double.

@kamcio96 can u help? :)

Still same problem. As is mentioned on the internet there couple of videos using this plugs/points to send energy to a draconic evolution energy core t8. But after 2,14 BRF the plugs refuse to send energy. This is kinda annoying...
