Im using Sky Factory 3 version 3.0.13, and i even updated to Flux Networks 1.2.5, it uses 1.2.4 by default. I would update it to 1.2.6, but that causes a crash on startup. Anyways, I hooked up a flux plug to the reactor rf port on my reactor, and one attached to an energy pylon to transfer the power over to my draconic energy core. It worked for a little while, but stopped suddenly and I haven't been able to get it working again. The core is at only 2.14 billion RF out of the 2.14 trillion RF it can support. Why isn't this working?

Are you using Draconic Evolution 2.1.6.263? I've found that version doesn't let a flux point interact with the pylon. Using 2.1.5.262 allows it.

Another workaround is putting an energy I/O crystal on the pylon and a flux point and linking the two crystals together. Make sure the bottom of the crystal is facing the connector to the flux point, and that one is on input mode and the other output.

I was using .263, I'll try .262 to see if it fixes the problem. It did work for a bit, and I even attached a second flux point to power my Refined Storage system, and it wasn't outputting any power.

Turns out the problem was my reactor. i broke the power tap and replaced it, that fixed the issue.
