I am trying to get forge for 1.12.2, but the game always seems to be crashing while loading. They appearently have trouble loading mipmaps. I tried multiple versions, with multiple ways to install it. Only the installer way seems to work, though, with other ways the Minecraft won't see it available. It seems to have problems with loading mipmaps.
