I've had no problems with Mekanism before now.
I have created an industrial turbine, then I placed down a basic universal cable attached to an energy storage block (can't recall the name). When I tried to set the cable to "pull", my game crashed. I now can not load my world.

Not sure what reports you need, hopefully these will suffice.

It looks like the turbine doesn't implement a certain interface. What mod is an "industrial turbine" from?

Mekanism v9?

Heh, sorry, I'm used to older versions. From looking through the source, I can't find a problem directly besides that maybe the turbine doesn't implement a few interfaces, but that seems unlikely. Good luck :)

Fixed in development.
