Hi everyone,
I've found a bug ?? or incompatibility with CC:Tweaked , with computer all of the storage block (or nuclear reactor ect...) is configurate like storage , so we have not methods to have Energy stored or a Capacity.
I'm already discuss with the discord's cc:tweaked and they say it must have an implementation.
So can you , or with me ,make all the storage blocks implemented :).

@CactusGame4 we do not have a Compat with CC:Tweaked.
And since we have our own EnergyAPI they simply either have to support our API or we do have to implement theirs, or a addon make support for it.

IC2Classic itself has atm no plans to actively support CC:Tweaked.
Though we would support with information if someone wants to make either the implementation in CC:Tweaked or make an addon.
