Help!

Yes, all my mods that are required to be together are together in the same folder, I always make sure of that. I also checked the broken mods and updated mods before I added any mods into my mods folder, I also always make sure to do that before I add any mods into my folder to save from any hassle. I also did the additive testing. I removed everything from the folder, started the game, added stuff back in, started the game, rinse and repeat. And like I said, the game works when the mods are split up, but not when they're all together :((

t0xic_sir3n_​ The 50-50 method works only if you keep together mods that require each other. If you don't, you will miss issues. Almost every set of instructions online skips that part. See vanilla and 50-50 testing

But also, start at Previously Broken mods and CC and Broken and Updated Mods and CC. If you still have issues after that and accurate 50-50 testing fails, you can do additive testing. Instead of gradually removing things, you gradually add them. When you get a failure, you might have a conflict. While you're adding batches, consider going to the mod pages to check installation instructions.
