Initially I tried to install the build, but I ran into a constant GalactiCraft error, after several shamanistic rites I took down all the mods and started running different versions of Galacti on different Forges and always one error. The only one that started was GalactiCraft Legacy, but alas, I need a later Forge. Please tell me what can be done
