Hello! I am trying to create a modpack to play with my friends, but first I started by modifying existing ones like Tekkit Legends and FTB Ultimate and everything ran with no problem, but the last mod I tried to add to FTB was IC2 (the same version installed in Tekkit Legends). The version in FTB was "Industrial-Craft-2-Mod-Experimental-1.7.10" and the one in Tekkit Legends "IC2.Classic.Version.220.127.116.11".
The problem comes in when I try to launch the game and it crashes, the crash report is attached since it was too long XD
It says the error comes from "ic2/core/block/machine/tileentity/TileEntityStandardMachine" which I saw is missing frome the IC2 classic files, I even tried copying it from the IC2 Experimental files and didn't work.
So I wanted to know if there's a way to solve my problem? Thanks!
