I used an electic wrench on a macerator and it gave me a machine block. The last time I had this bug was an earlier release and it was caused by an out of date Forge version, so that was the first thing I checked with this one. I'm using Forge 3.1.2.94.
Would ModLoaderMP cause this bug? At the time I downloaded all my mods, the instructions still included it. Once I have posted this, I'll be preparing and testing it without ModLoaderMP installed.
Anyone else having this bug?
