Issue
Mekanism Universal cable not connecting to IC2 reactor (maximum size). They can connect to any IC2 machines i own at the moment, my CESU as well, but can;t get it to connect to the reactor, turned on or off, tried every single side. IC2 cables are connecting.

Duplicate of #1116, I'm afraid we cannot fix this. Moving the machines to a different chunk and/or restarting the game sometimes helps.
