i have version 9.1.0.287 for 1.10.2 of mekanism and like the title says when i mine the energy pipes with a diamond pickax it causes a CTD i didn't have time to get the log as i am at work. ill get it as soon as i get home. also non-vanilla picks from silent gems mod mine it really slowly but don't cause a crash.
