Modpack version 1.9b.

Charged Draconium blocks are uncraftable because they require 10M RF/t but in
extendedcrafting.cfg combination_crafting.energy_capacity is set to 5M RF.
I can confirm that increasing this number (I tried 50M RF) works.

Already fixed in #175, thanks for the report anyway.

Did you try to craft it with the normal configs? The energy per tick shown in JEI is how much it accepts, not how much it requires.

Sorry, I didn't realize that this was already covered by the other issue. Yes, I tried crafting it with normal configs (where the internal buffer is 5M RF) and that didn't work. It said something like "not enough RF", although I fed it plenty of RF using an Energy Pylon from Draconic Evolution. I then changed the internal buffer size as mentioned and that immediately made it work without changing anything of my setup.

No worries :)

Hm, that doesn't sound good, I hope other recipes are fine.
