The Meaning of Life, the Universe, and Everything.
Which is the culprit for my screen becoming like this? Instead of showing the normal Forge screen with the initialization steps etc. I don't like these client side mods that think they're helping when they're actually not. And could modpack developers please stop putting client side mods in their packs? How about a list of links like "client side mods we thing you might like". Cause they ALL SUCK in my opinion and make my Minecraft perform horribly.
That looks the LiteLoader loading screen. LiteLoader mods are automatically clientside-only, so if you don't like those, you can probably disable LiteLoader safely, though the method for doing so depends on what launcher you're using. However, iirc one of the minimap mods only works with LiteLoader, so if you want to still use that mod but see the Forge loading screen instead, you can edit liteconfig/liteloader.properties and set "loadingbar=false".
