Apologies if this is a known issue, I tried searching through the forums, but couldn't find any post relating to this issue.
Basically what happens is that several of my machines (forestry, IC2 etc) stop receiving energy through my network after I go to the Nether and back. I've tried putting steam engines in between my conduits just so see if my combustion engines were malfunctioning, but the issue seems to be that the machines just don't want to accept any power after I change dimensions.
I also tried putting a chunk loader in the area, but it didn't solve anything :-(
Any ideas how to fix this? A server restart fixes the issue every time, but that seems excessive after every trip to the Nether...
