on the latest version (3.0.13) , whenever i connect a flux plug to any generator , on the display, it reads the energy source as FE, but then the plug itself reads as RF, but with twice the amount of energy. i tested this with multiple energy storages to make sure it's not just a visual bug and it is indeed doubling the amount of energy when converting from FE to RF. if i disable conversion, then no energy is transfered. flux points are transferring energy normally. checked the config files, and both FE and RF are set to 1.0 . what's really weird is that blocks that usually say they produce RF on the gui ( thermal expansion dynamos, nuclearcraft reactors, solar panels, etc) are being read as FE by the flux plugs. changing back to version 3.0.11 fixes this.

The transfers were indeed 512KRF/t when output was limited to 256KRF/t

Also breaking the storage still deletes the energy.

i'll try updating back to the newest version and doing some more testing. the only testing i was able to do before involved fluxducts and a rftools power storage with the screen. the flux points connected to the power storage by a fluxduct inserted the power, and the screen read that the storage was receiving double the power that the generators were producing. if the screen is also a visual bug, then that means that flux points are also displaying this bug, although only visually.

alright, did some testing. turns out the issue purely visual as you said, my screen that was also displaying the bug because i had a complicated setup with multiple networks where it was reading the energy transfer from the generators and the insertion on the power storage, must have forgotten to turn of the reading of the generators when i switched power storage. actual numbers are normal, just the flux plug that is displaying the added amounts. thank you.

I believe this is only a visual issue, and the amount of energy being sent is not doubled, but the energy transfers are being added together, can you check if energy is actually being duplicated?
