Version 1.0.7f

It seems that neither the buffer nor the block-extender seems to accept any kind of RF power. I tried with connecting galacticcraft-wires, energy transfernode+energy pipe (extra utilities) and an energy-cell (thermal expansion). The buffer seems to "see" what is connected, but cannot put the energy through at all.
(the huge buffer stays at 0 as well... actually not sure if the buffer is a bug in waila, it shows over 21 million rf or so as buffer)

Could you post the mods list? I have a hard time finding out what causes this as it seems like there's nothing wrong when I try.

Post a screenshot of a setup that doesn't work.

It seems to be to do with the item/mod that is receiving power. If I place an energy cell, then any power cable then extender and then item to receive power. If the item is a machine from thermal expansion or the energy acceptor from AE2 the cable does not connect to the extender and no power is transferred. If I place an TE energy cell, or a gendustry apiary then the cable connects and power transfers.

I think I figured it out. TE split up the EnergyHandler into an EnergyReceiver and an EnergyProvider, but kept the EnergyHandler which extends both EnergyReceiver and EnergyProvider, which means that there will be no crash, but when something only implements EnergyReceiver Refined Relocation will not send power. Should be an easy fix!
