Haven't played this mod for a while, but I noticed basic components seems to be gone from Galacticraft? Before trying the 1.6.4 version of Galacticraft I tried Voltz, in which I used the battery box and copper wire from Basic Components to store and transfer energy. But because it seems to be missing in 1.6.4, I have no good way to use energy. I found Galacticraft now has a energy storage module - which seems to be the replacement of the battery box - and aluminium wire. But when using energy made by for example a wind mill (which I think is part of Mekanism?), it won't go in the energy storage module, although all wires seem to connect. Only power made from solar panels (from Galacticraft, not the Mekanism ones) seem to work with the energy storage box. I know Basic Components was removed from UE from 1.5.2 and onwards, but is there a way to re-enable them in 1.6.4 with Galacticraft? I can't seem to find a config option for it. EDIT: Also, when following the video Micdoodle linked, he was given a popup in which to enable Basic Components. I do not have that option. The only thing I have installed at the moment is Forge 188.8.131.525, Galacticraft v184.108.40.2068, MicdoodleCore v220.127.116.118, and Galacticraft Planets v18.104.22.1688.
