Hi, sorry if this is in the wrong place. I'm trying to add Mekanism to my modpack. I feel as though this would be an essential mod for me to add. My modpack can be found here with a mod list. The problem I'm getting is when I add Mekanism (Yes it's the 1.6.4 version like all the other mods), it downloads ForgeMultipart-universal-1.6.4-1.0.0.219.jar upon starting minecraft. One of my other mods downloads ForgeMultipart-universal-1.6.4-1.0.0.182.jar and this causes a duplicate file crash preventing the game from being played. All my other mods are important that they be in the modpack, but I cannot install Mekanism. Any ID problems I can fix, but this is baffling me. Thank you for your help if you can provide it.
