recently logged on to my world and realised the shaft closest to my flywheel between the flywheel and speed controller had been broken. And the rest of them were spinning at the same speed as the output of the speed controller. tried to track the source of this infinite power back through the contraption but gave up since it´s a mess.

playing the minecraft create; above and beyond modpack, release version 3. Timeline leading up to event was: had minecraft minimized being afk, noticed i had crashed (java exception null something, seem to recall a 1 as well), started minecraft, world loading stuck at 100% so forced closed. Started again and entered world no problem and issue still remains.

solved, was an issue of "ghost power". Found a loop of power by turning on debug and using F3. solved it by breaking and replacing a part of the loop.
