Alright so when i place at least your universal cable and try to break it with my pickaxe it crashes everytime. No its not cause of another mod. i have tryed mekanism by itself completely and done the same thing and it still crashes

same as #3545 can confim it happens with every pick at but the paxel. Happens with all pips and cables

McMultipart issue. @amadornes, any luck with the crash in #3545?

can confirm installing McMultiparts (non-experimental) fixed issue, i forgot to install in #3545. mek also doesn't tell me that it was missing despite it being a prerequisite.

Strange. It's automatically installed on runtime, Minecraft wouldn't launch without McMultipart installed, I'm surprised there was no mod conflict upon your installation.

One thing i did notice is that it creates a 1.10 folder that has mc mp in it. It was an experimental version. i Deleted it and redownloaded a version on curse using the minecraft client. The crash then stopped. Maybe the version that is downloaded with the runtime contains the bug. The conflict happened the first time i downloaded mcmp and it said i had 2 versions.
