I've been having this interesting issue with the latest version of Tekkit where my redstone energy cells in the Nether stop functioning. They are connected to a pump, which gathers lava, sends it to the overworld, where it is pumped into Magmatic engines for usable energy for later. In the nether, each pump (currently only one pump is active while troubleshooting) has it's own Chunk Loader, yet after a very short amount of time, it randomly ceases to function. I was wondering if you guys could offer any help.
