I'm currently playing FTB Revelations and I'm trying to get a basic reactor up and running. I created a (really) simple 5x5x5 design in the big reactors simulator, and it states it should produce around 7KiRF/tick without any coolant. I created the exact same design in-game, but I can't seem to get even close to the same results as stated on the simulator (see screenshot). Has something been nerfed? Or am I just missing something? Spoiler: Screenshot Edit: I thought it might be worth mentioning that it doesn't currently have any cooling (like in the simulator). Just don't want any confusion from JEI. Also, control rods are all at 0%.
