With the lastest versions of Mekansim I have noticed a bug where all machines from Mekanism and Mekanism Generators appear asUnnamed both in-world, in inventory and in NEI. No, I do not have Waila installed.

There was nothing out of the ordinary until yesterday when i booted up and everything was unnamed, and makanism machines nolonger accepted items through pipes of any kind (hoppers don't work wither). I have tried a clean install aswell.

Mekanism version: 7.0.0.75 & 7.0.0.82

Seems like a definite non-Mekanism issue, most likely another mod is interfering with Mekanism's naming. Unless you can reproduce the issue with a fresh install of Forge with no other mods installed, I can't do much.
