Hi,

I have created my own modpack and I am constantly encountering the error "fml.modloading.dupedmod." I have checked all of my mods 3 times and there are no duplicates. I have read on the internet that I need to remove JEI, which I have already done and it resolved the issue. However, I need JEI as it is the best mod and I cannot play without it. Is there any other way to resolve this error without having to remove JEI or a less important mod?
