So... i had Forge for many time and a week ago i tried to add some mods and when i opened the game i saw that some of the mods are not supported. so i went to the appdata files and i deleted some folders and files then when i opened the game, after loading the "Mod phase 3" the game crushed. I thing i deleted something that made forge to crush... I tried to re-install forge and i removed all mods from the 'mods' file but that still didn't work. (that happend only in forge) Please help. Thank you. p.s that wrote::: "The game crashed whilst initializing game Error: java.lang.ArrayIndexOutOfBoundsException: 3"
